Bed: The bed of the planer must be a weldment or casting twice as long as the table. [2] However, Roe (1916) credits James Nasmyth with the invention of the shaper in 1836. The cutting tool is also gear shaped having the same pitch as the gear to be cut. Shaper Size: The size of a shaper is the maximum length of stroke which it can take. The work piece is rigidly held in a vice or clamped directly on the table. With a clamping force of 4,500 N and a repeat accuracy of 0.02 mm, the low-maintenance PGS3 is suitable for basic applications in machining aluminum and plastics. These parts are usually large iron castings or steel weldments and may weigh a few hundred pounds or several tons. Forward Stroke O B. The stroke per minute available on a shaper will vary according to the size of the shaper. However, it is a production-- type machine for certain types of work. Other examples of its use are: Samuel Bentham developed a shaper between 1791 and 1793. When acquiring a shaper, and with the unit disconnected from a power source, manually turn the external drive wheel and observe the action of the table in relation to the ram's stroke. Copy and "Paste in Place" the shape so that it will overlape the first shape and make it a totally different color. The most frequently used type of planer is the double-housing planer. The ram reciprocates and the cutting tool, held in the tool holder, moves forwards and backwards over the work piece. Double-housing Planers: Double-housing planers consist of a long heavy base on which the table reciprocates. Cutting Speed: The cutting speed of the tool across the work will vary during the stroke as shown by the velocity diagram. At the front end of the ram is a vertical tool slide that may be adjusted to either side of the vertical plane along the stroke axis. Moving the tool bit attached to the ram makes the cutting stroke of the shaper. Coarse feeds for roughing range up to 0.100- per stroke (sometimes abbreviated as IPS), and finish cuts from 0.005- to 0.015" per stroke. The cutter is sharpened with rake and clearance angles similar to lathe tools though the angles are smaller because the work surface is usually flat. Thus a 12-foot table requires a 24foot bed. Owing to the reciprocating action of the cutter, there is no cutting on the return stroke in the gear shaper. Estimate the machining time assuming an average cutting speed of 20m/min and a feed of 0.2 mm/stroke. The ram slides back and forth above the work. Crossrail: The crossrail is also a heavy box, or similar construction. Table: The table is a heavy casting which carries the work past the cutting heads. Typical work would be machine beds and columns, marine diesel engine blocks, and bending plates for sheet-metal work. Thus they are still popular in many machine shops, from jobbing shops or repair shops to tool and die shops, where only one or a few pieces are required to be produced and the alternative methods are cost- or tooling-intensive. A shaper is a type of machine tool that uses linear relative motion between the workpiece and a single-point cutting tool to machine a linear toolpath. This return stroke is governed by a quick return mechanism. However, the return stroke is made at up to twice speed of the cutting stroke. The SCHUNK Tandem PGS3-LH 100 can be mounted directly via the integrated flange on the machine tables, dividing heads or SCHUNK Vero-S NSL3 150 clamping stations of machining centers. The speed is expressed in metre per minute. This tool-slide holds the clapper box and tool post, from which the tool can be positioned to cut a straight, flat surface on the top of the workpiece. As the ram reciprocates, the tool cuts the material during its forward stroke. The return is governed by a quick return mechanism. Although the ratio varies somewhat, several shapers have a linkage using 220 degrees of the cycle for the cutting stroke and 140 degrees for the return stroke. Work that cannot be held in the vise (due to size or shape) is clamped directly to the shaper table in much the same way as parts are secured on milling machine tables. chart such as the one shown in table 9-1. cut. The return is governed by a quick return mechanism. In shaper, feed is normally given to the work piece and can be automatic or manual. Question: In Shaper Machine The Metal Cutting Can Be Done In The Following Stroke Select One: A. Upward Direction B. The ram holding the tool reciprocates over the workpiece and metal is cut during the forward stroke called a cutting stroke and; No metal is cut during its return stroke is called an Idle stroke. Hydraulic Drive A slotter is fixed in the vertical plane. The planer handles work weighing up to several tons. Workholding: Holding the work while machining such heavy cuts at 60 to 100 feet per minute requires considerable force; therefore, the workpieces must be solidly fastened to the table. This creates a very strong, rigid structure that will handle heavy loads without deflection. Special quality features include a chip-repelling design, the surface-treated components in the power flux, and the fact that the long base jaw guidances avoid lifting of the chuck jaws. They also have considerable retro appeal to many hobbyist machinists, who are happy to obtain a used shaper or, in some cases, even to build a new one from scratch. The cutting speed is changed by controlling the throttle valve which controls the flow of oil. The cutting stroke of the planer is achieved by moving the work past a stationary tool bit. Vertical shapers are generally fitted with a rotary table to enable curved surfaces to be machined (same idea as in helical planing). How to Create the Text.  The shaper mechanism is made so that it moves the ram holding the tool at a comparatively slower speed during forward stroke, whereas during the return stroke it allows the ram to move at a faster speed to reduce … Both the shaper and the planer are single-point tools that cut only in straight lines:The shaper handles relatively small work. Attached to the toolhead is the toolholding section. Railheads: The two railheads can be moved left or right across the crossrail, each controlled by a separate lead screw, which can be turned by hand but usually by power feed. Description of Parts of Shaping Machine with its Functions It's principal components are shown here. Tools used in shaper and planer work are single point as used on a lathe, but are heavier in construction. A metalworking shaper is somewhat analogous to a metalworking planer, with the cutter riding a ram that moves relative to a stationary workpiece, rather than the workpiece moving beneath the cutter. The earlier illustration shows how the tools are supported both above and on the sides, and their adjustment for angle cuts. In other words, the ram of the shaper moves a single point cutting tool back-and-forth, and on each forward stroke, the tool removes a chip of metal from the workpiece. The ram is adjustable for stroke and, due to the geometry of the linkage, it moves faster on the return (non-cutting) stroke than on the forward, cutting stroke. The block holding the tool post can be rotated a few degrees so that the cutter may be properly positioned in the cut.The horizontal shaper is the most common type. They differ greatly in construction and in the method of operation. The vertical shaper is essentially the same thing as a slotter (slotting machine), although technically a distinction can be made if one defines a true vertical shaper as a machine whose slide can be moved from the vertical. Coarse feeds for roughing range up to 0.100- per stroke (sometimes abbreviated as IPS), and finish cuts from 0.005- to 0.015" per stroke. Most planers have one flat and one double V-way, which allows for unequal bed and platen expansions. Often this clapper box is automatically raised by mechanical, air, or hydraulic action. Shapers are mainly classified as standard, draw-cut, horizontal, universal, vertical, geared, crank, hydraulic, contour and traveling head,[1] with a horizontal arrangement most common. The cutting time to return time ratio is given to be 1.5 and the ram cycles available on the shapers are 28,40,60 and 90 per minute. Shaper Width: The maximum width which can be cut depends on the available movement of the table. This specifies the approximate width of the table which ranges from 30" to 72". The motor driving the pinion gear is the reversible type with variable speed. All of our … The mechanism for moving the ram and table is housed inside the column. The hydraulic shaper has the same major parts as the mechanical one; however, the ram is driven by a hydraulic cylinder as shown in the simplified sketch. Such calculations are beyond the scope of this text. But in slotter machines, the direction of cutting stroke is vertical with slower than the return stroke. Let's go through the components of Cut mode in detail. Speed and feed on a hydraulic shaper are often controlled by simple dials. side of the shaper, lets you change the speed of the ram ... cutting stroke consumes 3/5 of the time and the return. It can take heavy cuts with 'less vibration and strain on the work table. In current industrial practice, shapers have been largely superseded by other machine tools (especially of the CNC type), including milling machines, grinding machines, and broaching machines. Table: The table is moved left and right, usually by hand, to position the work under the cutter when setting up. © 2021 Endeavor Business Media, LLC. The table may be supported at the outer end. Clapper Box: The clapper box is needed because the cutter drags over the work on the return stroke. It was discontinued in the year of 1961. Know your Shaper – Details on the Atlas Shaper by Sam Brown; Contour Cutting with the Atlas Shaper by Sam Brown; History. Saddle: The saddle moves up and down (Y axis), usually manually, to set the rough position of the depth of cut. Horizontal feed rates of up to approximately 0.170. The default is … It is expressed in mm/double stroke or simply mm/stroke because no cutting is done in return stroke Most shapers have a width capacity equal to or greater than the length of the stroke. In a standard shaper, cutting of material takes place during the forward stroke of the ram and the return stroke remains idle. Toolhead: The toolhead is fastened to the ram on a circular plate so that it can be rotated for making angular cuts. A wood shaper is a functionally different woodworking tool, typically with a powered rotating cutting head and manually fed workpiece, usually known simply as a shaper in North America and spindle moulder in the UK. In the Stroke panel, you can choose to change the Width height by clicking and selecting a preset width from the Width drop-down menu, or you can type in a value. Tooling is simple, and shapers do not always require operator attention while cutting. just as in the lathe, but in a vertical plane. Horizontal shapers are most often made with strokes from 16- to 24" long, though some smaller and larger sizes are available. Next, determine the ram stroke speed by using the. Metal Shaper In Metalworking Lathe Tooling, 100mm Stroke Industrial Linear Actuators, 1500mm (60 in) Stroke Industrial Linear Actuators, 400mm (16 in) Stroke Industrial Linear Actuators, 500mm (20 in) Stroke Industrial Linear Actuators, Metal Cutting Metalworking Manuals, Books & Plans, 200mm (8 in) Stroke Industrial Linear Actuators The bull gear is driven by a pinion which is connected to the motor shaft through a gear box with four, eight or more speeds available. Plan Your Message, Schedule, and Adapt for Success. The railhead can be rotated, and vertically adjusted for depth of cut, the same as the shaper heads. But the basic function of a shaper is still sound; tooling for them is minimal and very cheap to reproduce; and they are simple and robust in construction, making their repair and upkeep easily achievable. Another method is to have the rate of fluid flow increased to speed up the return stroke. The table is driven either by a very long hydraulic cylinder or by a pinion gear driving a rack, which is fastened under the center of the table. These cutters are fastened into the toolholder. Length of stroke is controlled by how far out you wind the drive pivot on the bull gear. Figures below show diagrams of both shaper drive mechanisms. Shapers are available with either mechanical or hydraulic drive mechanisms. Learn more at www.schunk.com, For more new products, visit newequipment.com, Sign up for American Machinist eNewsletters. This drive uses a crank mechanism. They also have a clapper box (often with power lift) like the shaper. Cutting Feed: Feed per stroke on a shaper is comparable to the feed per revolution on a lathe. The name shaper relates to the fact that the cutter engages the part on the forward stroke and pulls away from the part on the return stroke, just like the clapper box on a planer shaper. Finish would also depend on the nose radius of the cutting tool. Cutting tools for the planer operation are usually tipped with high-speed steel, cast alloy, or carbide inserts. Maintenance Improvement B. Cutting speeds are affected by the rigidity of the machine, how the work is held, tool, material, and the number of tools in operation. Uniform cutting speed is attained throughout the cutting stroke. Step 1. The Expand Stroke does exactly what it says - it expands the stroke of a shape or line turning it into a shape itself. The shaper handles relatively small work. A more complete specification is: Width of table x height under rail x length of table (For example: 48" x 48" x 14 feet). No Cutting Possible O C. Upward Direction O D. Reverse Stroke In a standard shaper, cutting of material takes place during the forward stroke of the ram and the return stroke remains idle. The gearing of hydraulic cylinders for driving the table is housed under the bed. The forward and backward motion is obtained by “Quick Return Mechanism”. No Cutting Possible C. Reverse Stroke D. Forward Stroke The Following Maintenance Type Is Used To Modify And Increased Reliability And Easier Maintenance Of Equipment Select One: A. The drive on the planer table is either by gears or by hydraulic means. Reciprocating movements over the work piece results in forward and backward strokes. It runs on V- or flat ways. This machine can work either outside or inside a part, provided that the interior opening is larger than the tool head. The vertical shaper, sometimes called a Blotter, has a vertical ram, with table and saddle similar to the horizontal shaper. Forward stroke is responsible for cutting action over the object and backward movement is responsible for restoring its position without any cutting action. Cutting angles for tools depend on the tool used and the workpiece material. The most common use is to machine straight, flat surfaces, but with ingenuity and some accessories a wide range of work can be done. public System.Windows.Media.Brush Stroke { get; set; } member this.Stroke : System.Windows.Media.Brush with get, set Public Property Stroke As Brush Property Value Brush. Toolholders: Toolholders are the same as the ones used on at engine lathe, though often larger in size. Solution for The shaper mechanism is designed to give a slow cutting stroke and a quick return to a blade attached to the slider at C. Determine the angular… These crossrails are so heavy that they are counterweighted, with either cast iron weights or hydraulic cylinders, in order that they may be moved easily and positioned accurately. Adjustable dogs at the side of the bed control the stroke length of the platen. He is the Professor Emeritus of Engineering Technology at Lawrence Technological University, and former Chairman of the Detroit Chapter of the Society of Manufacturing Engineers. An SVG's size can be increased or decreased without a loss of quality. Determine the cutting speed and material removal rate for shaper operating at 2 cutting strokes/sec to machine a workpiece of 300 mm length at a feed of 0.4 mm/ stroke and 6 mm depth of cut. George Schneider, Jr., is the author of Cutting Tool Applications, a handbook to machine tool materials, principles, and designs. Open the door, and you will see the screw that adjust this. They both make the same types of cuts. The vise can be immediately incorporated into any machine tool: it has lateral air connections and built-in keyways. The RPM of the bull gear becomes the strokes per minute (sometimes abbreviated SPM) of the shaper. Its cut is analogous to that of a lathe, except that it is (archetypally) linear instead of helical. Open-sided Planers: Open-sided planers have the housing on one side only. Cut mode is the heart of Shaper Origin. According to the National Stroke Association, stroke is the third-leading cause of death in the U.S. Every year, about 750,000 Americans suffer a stroke, and about 160,000 die from one. Vertical Shapers They are fed by power in either a vertical or a crosswise direction. Applications of gear shaping:-1) Cutting spur gears In a standard shaper, cutting takes place during the forward stroke of the ram and the backward stroke remains idle. The table has T-slots, both lengthwise and across, in which heavy bolts and clamps may be used. The rate of production is lower than the gear hobbing process due to periodical indexing hence; More machining time. The toolhead can also be moved up or down by its hand crank for precise depth adjustments. shaper. A shaper machine is working on the following principle: A shaper machine holds the Single point cutting tool in ram and workpiece is fixed over the table. Worktables on planers and shapers are constructed with T-slots to hold and clamp parts that are to be machined. Compact, square workholding device has an integral flange, so it can be mounted directly to the machining table for optimal accessibility and a 6-mm per jaw stroke. In other words, only the forward cutting stroke is considered. The depth of the cut is adjusted by moving the tool downwards towards the work piece. Let's obtain the letters that we need to create this text effect. The depth of the cu… Once you've scanned your workspace and placed designs, switch to Cut mode. A single-point cutting tool is rigidly held in the tool holder, which is mounted on the ram. On the left-hand side (top to bottom) you'll see the following settings: Table motion may be controlled manually, but is usually advanced by an automatic feed mechanism acting on the feedscrew. The cutting speed remains nearly constant through the full stroke. The working of shaper machine can be described as follow. Cut Settings. Its compact and square design ensures optimal accessibility and enables a stroke of 6 mm per jaw. What type of material are you cutting, how much depth, what kind of cut (standard flat, dovetail, etc.) Worms & Worm wheels cannot be generated on gear shapers. It is used fairly often in the toolroom or for machining one or two pieces for prototype work. These shapers use from 2- to 5-hp motors to drive the head and the automatic feed. Sometimes holes are drilled in the table so that large pins can be used to prevent the workpiece from going off the table when the machine reverses. ... many strokes for the 4-inch cut as it does for the 12-inch. Drive Mechanisms Rake relief angles are similar to those used on lathes for cutting cast iron or steel, although relief angles are often only 3 to 5 degrees, because all cuts are on flat surfaces. Shaper Mechanism 31  In a standard shaper metal is removed in the forward cutting stroke, while the return stroke goes idle and no metal is removed during this stroke. To vary the position, you use the lock levers on the top of the ram. Ans: choosing 28 strokes/min, time=44.65min Adding axes of motion to a shaper can yield helical toolpaths, as also done in helical planing. It cuts the metal in one stroke in back motion or in froth motion and the remaining one is useless. The tool-slide permits feeding the tool downwards to deepen a cut. This is close to a 3:2 ratio. The less expensive shaper, the one most often purchased, uses a mechanical drive. The horizontal shaper is the most common type, and its principal components are shown below, and described as follows: Ram: The ram slides back and forth in dovetail or square ways to transmit power to the cutter. However, if the cutting speed chosen is somewhat on the slow side, the average speed may be used, and computations are greatly simplified. Free Download Abstract image, a triangular shape, with stroke Free SVG Cut Files. In this example, we'll be cutting the peg board project from ShaperHub. The horizontal shaper is the most common type. The work piece is rigidly held in a vice or clamped directly on the table. The vise is specially designed for use in shapers and has long ways which allow the jaws to open up to 14" or more, therefore quite large workpieces can be held. A planer makes the same types of cuts as a shaper. This has a tool post very similar to that used on the engine lathe. Frame: The frame is basically two heavy columns fastened together at the top with a large bracing section and fastened at the bottom to the machine bed. Since planers make heavy cuts, their tools are much larger. Create a circle or any shape as a path NOT a stroke. Cutting Feed: Feed per stroke on a shaper is comparable to the feed per revolution on a lathe. The height of the table can be adjusted to suit this workpiece, and the table can traverse sideways underneath the reciprocating tool, which is mounted on the ram. All rights reserved. These shapers use 5- to 10-hp motors. Cutting is done during the return stroke as the tool is set in a reversed direction to that of the standard shaper. The maximum is at the center of the stroke. Workholding: Workholding is frequently done in a vise. The vise may also have a swivel base so that cuts may be made at an angle. Both the shaper and planer usually cut only in one direction, so that the return stroke is lost time. Table length is often made to order and may be as short as 8 feet, or as long as 20 feet or more. Sideheads: The sideheads are independently moved up or down by hand or by power feed and can also be rotated and moved in or out for depth of cut. Speed is read directly in feet per minute and feed is read directly in decimal inches. A 16" shaper may have speeds of 27 to 150 strokes per minute, while a 24- shaper will have 10 to 90 strokes per minute speeds available. The ram is typically actuated by a mechanical crank inside the column, though hydraulically actuated shapers are increasingly used. They are similar to angles used on other single-point tools, but the end clearance does not exceed 4 degrees. Although both the planer and the shaper are able to machine flat surfaces, there is little overlapping in their application. Automatic Table Feeding Mechanism of Shaper. Grab … Planers are often converted to planer-- mills, for more efficient machining. The maximum vertical height available is about 12" to 15". [3] Shapers were very common in industrial production from the mid-19th century through the mid-20th. Shaper machine is used to produce horizontal, vertical or inclined flat surfaces. Planer Size: The size of planers is often referred to as a 30" planer or a 60- planer. Most planers differ from shapers in that they approach more constant-velocity cutting speeds. Using the pen tool, select a new stroke color (red with no fill in this example) and trace the center line. Now suppose you want to adjust it boundaries: you can't because it's still a line (an open path). The workpiece mounts on a rigid, box-shaped table in front of the machine. Acceleration and deceleration of the table takes place in a short distance of travel and does not influence the time to machine. The reciprocating motion of the ram is obtained by a scotch yoke mechanism. The planer is especially adapted to large work: the shaper can do only small work. For example draw a line and change its pressure curve in the stroke width pop-up in the context toolbar to create a tapered line. The shaper is a relatively simple machine. The Planer SVG cut files are a graphic type that can be scaled to use with the Silhouette Cameo or Cricut. The planer handles work weighing up to several tons. The open side permits machining wider workpieces. You can also customize the caps (the end of a line), joins (the endpoints of a path or dash), and the miter limit (the length of a point). Mechanical and hydraulic power can be used for planers. The planer handles work weighing up to several tons. Because the reversal of direction occurs quite rapidly, the work must be especially well braced at the ends. It's principal components are shown here.Cincinnati Machine. In setting up a mechanically operated shaper, the length of cut (in inches) is known, and the cutting speed (in feet per minute) is selected according to the kind of metal being cut. harvnb error: no target: CITEREFRoe1916 (, Lathes.co.uk information archive on hand-powered shapers, YouTube video of a vintage shaper in action, YouTube video of a newly built hobbyist shaper in action, https://en.wikipedia.org/w/index.php?title=Shaper&oldid=971268136, Short description is different from Wikidata, Creative Commons Attribution-ShareAlike License, Keyway, spline, and gear tooth cutting in, Cam drums with toolpaths of the type that in CNC milling terms would require 4- or 5-axis contouring or turn-mill cylindrical interpolation, This page was last edited on 5 August 2020, at 02:28. Question: In Shaper Machine The Metal Cutting Can Be Done In The Following Stroke Select One: O A. When the throttle valve is lost the excess oil flow cut through the relief valve to the reservoir maintaining uniform pressure during the cutting stroke. 5: Make the stroke match the cutter. In a standard shaper, metal is removed in the forward cutting stroke, while the return stroke goes idle and no metal is removed during this period. Shaper machine works on the quick return mechanism. The table may be supported at the outer end. The upright housing near the center on the side of the base, supports the crossrail on which the tools are fed across the work. You can also use the "Pathfinder" tool to cut out any shape to make it look like an outlined stroke. The starting point and the length of the stroke can be adjusted. If a rotary table is mounted on the regular table, a number of slots can be made at quite accurately spaced intervals. It is used to shape the metal or make flat surfaces, making grooves and slots. The drive may be 15 hp on the smaller planers, and 100 hp or more on the larger models. Column: The column supports the ram and the rails for the saddle. Both the shaper and the planer are single-point tools that cut only in straight lines. Then, either by hand or more often automatically, the table is moved sideways to feed the work under the cutter at the end or beginning of each stroke. Shaper are often converted to planer -- mills, for more efficient machining more machining. `` Pathfinder '' tool to cut out any shape as a shaper do!
