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. Adding axes of motion to a shaper can yield helical toolpaths, as also done in helical planing. Double-housing Planers: Double-housing planers consist of a long heavy base on which the table reciprocates. 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. Toolhead: The toolhead is fastened to the ram on a circular plate so that it can be rotated for making angular cuts. However, if the cutting speed chosen is somewhat on the slow side, the average speed may be used, and computations are greatly simplified. George Schneider, Jr., is the author of Cutting Tool Applications, a handbook to machine tool materials, principles, and designs. 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. It was discontinued in the year of 1961. The vertical shaper, sometimes called a Blotter, has a vertical ram, with table and saddle similar to the horizontal shaper. Vertical Shapers The starting point and the length of the stroke can be adjusted. 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. Forward stroke is responsible for cutting action over the object and backward movement is responsible for restoring its position without any cutting action. The railhead can be rotated, and vertically adjusted for depth of cut, the same as the shaper heads. 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. 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. It is expressed in mm/double stroke or simply mm/stroke because no cutting is done in return stroke After being positioned, they are clamped in place. Speed and feed on a hydraulic shaper are often controlled by simple dials. Most planers have one flat and one double V-way, which allows for unequal bed and platen expansions. The cutting speed remains nearly constant through the full stroke. On the left-hand side (top to bottom) you'll see the following settings: In a standard shaper, cutting of material takes place during the forward stroke of the ram and the return stroke remains idle. In this example, we'll be cutting the peg board project from ShaperHub. ... many strokes for the 4-inch cut as it does for the 12-inch. Its cut is analogous to that of a lathe, except that it is (archetypally) linear instead of helical. Mechanical Drive Planer Size: The size of planers is often referred to as a 30" planer or a 60- planer. The shaper ram also can be driven in this manner, but many times a quick-return link mechanism is used. It cuts the metal in one stroke in back motion or in froth motion and the remaining one is useless. The speed is expressed in metre per minute. A single-point cutting tool is rigidly held in the tool holder, which is mounted on the ram. Finish would also depend on the nose radius of the cutting tool. The mechanism for moving the ram and table is housed inside the column. 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. [2] However, Roe (1916) credits James Nasmyth with the invention of the shaper in 1836. The planer is especially adapted to large work: the shaper can do only small work. The drive on the planer table is either by gears or by hydraulic means. A more complete specification is: Width of table x height under rail x length of table (For example: 48" x 48" x 14 feet). Let's obtain the letters that we need to create this text effect. The ram slides back and forth above the work. Finish would also depend on the nose radius of the cutting tool. Both the shaper and planer usually cut only in one direction, so that the return stroke is lost time. 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. 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. To vary the position, you use the lock levers on the top of the ram. 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. They also have a clapper box (often with power lift) like the shaper. The work piece is rigidly held in a vice or clamped directly on the table. They both make the same types of cuts. Cutting Feed: Feed per stroke on a shaper is comparable to the feed per revolution on a lathe. Column: The column supports the ram and the rails for the saddle. 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. Tools used in shaper and planer work are single point as used on a lathe, but are heavier in construction. The most frequently used type of planer is the double-housing planer. Crossrail: The crossrail is also a heavy box, or similar construction. In a standard shaper, cutting of material takes place during the forward stroke of the ram and the return stroke remains idle. Table length is often made to order and may be as short as 8 feet, or as long as 20 feet or more. 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… Both the shaper and the planer are single-point tools that cut only in straight lines:The shaper handles relatively small work. The tool-slide permits feeding the tool downwards to deepen a cut. They are fed by power in either a vertical or a crosswise direction. 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. It runs on V- or flat ways. It's principal components are shown here. The horizontal shaper is the most common type. These shapers use 5- to 10-hp motors. All rights reserved. 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. Saddle: The saddle moves up and down (Y axis), usually manually, to set the rough position of the depth of cut. Estimate the machining time assuming an average cutting speed of 20m/min and a feed of 0.2 mm/stroke. 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. Table: The table is a heavy casting which carries the work past the cutting heads. 27. Cutting Feed: Feed per stroke on a shaper is comparable to the feed per revolution on a lathe. Cutting Speed and Feed: The cutting speed of the hydraulic shaper is infinitely variable by means of hydraulic controls, as is the cross feed. Often this clapper box is automatically raised by mechanical, air, or hydraulic action. The depth of the cu… The single point cutting tool held properly in the tool post is mounted on a reciprocating ram. 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. 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. Table motion may be controlled manually, but is usually advanced by an automatic feed mechanism acting on the feedscrew. 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. The gearing of hydraulic cylinders for driving the table is housed under the bed. 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. The working of shaper machine can be described as follow. Mechanical and hydraulic power can be used for planers. Uniform cutting speed is attained throughout the cutting stroke. An SVG's size can be increased or decreased without a loss of quality. Cutting angles for tools depend on the tool used and the workpiece material. Atlas started manufacturing the 7 inch shaper in 1937 which sold for $198.00. Cutting Speed: The cutting speed of the tool across the work will vary during the stroke as shown by the velocity diagram. 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. It is then necessary to compute the strokes per minute since that is how the shaper speed is controlled. The table may be supported at the outer end. The reciprocating motion of the ram is obtained by a scotch yoke mechanism. Final depth can be set by the hand crank on the tool head. Shaper Width: The maximum width which can be cut depends on the available movement of the table. Both the shaper and the planer are single-point tools that cut only in straight lines. In other words, only the forward cutting stroke is considered. 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. This specifies the approximate width of the table which ranges from 30" to 72". 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. 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. Drive Mechanisms The table has T-slots, both lengthwise and across, in which heavy bolts and clamps may be used. The cutting speed of a shaper is the speed at which the metal is removed by the cutting tool in one minute. Now suppose you want to adjust it boundaries: you can't because it's still a line (an open path). Create a circle or any shape as a path NOT a stroke. 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. [3] Shapers were very common in industrial production from the mid-19th century through the mid-20th. Maintenance Improvement B. Upward Direction B. Question: In Shaper Machine The Metal Cutting Can Be Done In The Following Stroke Select One: O A. 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. 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 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. They differ greatly in construction and in the method of operation. Toolholders: Toolholders are the same as the ones used on at engine lathe, though often larger in size. Cut mode is the heart of Shaper Origin. 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. In shaper, feed is normally given to the work piece and can be automatic or manual. 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. Question: In Shaper Machine The Metal Cutting Can Be Done In The Following Stroke Select One: A. This creates a very strong, rigid structure that will handle heavy loads without deflection. Toolholders: Planers use high-speed steel or carbide tipped cutting tools similar to those used on shapers. 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. 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. The stroke per minute available on a shaper will vary according to the size of the shaper. The rate of production is lower than the gear hobbing process due to periodical indexing hence; More machining time. Acceleration and deceleration of the table takes place in a short distance of travel and does not influence the time to machine. Since planers make heavy cuts, their tools are much larger. Adjustable dogs at the side of the bed control the stroke length of the platen. Comparison of Shapers and Planers 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. Determine the time to machine the component with width of 150 mm. A slotter is fixed in the vertical plane. Horizontal shapers are most often made with strokes from 16- to 24" long, though some smaller and larger sizes are available. It can machine any flat or angular surface, including grooves and slots, in medium and large sized workpieces. Workholding: Workholding is frequently done in a vise. Grab … Shaper Size: The size of a shaper is the maximum length of stroke which it can take. This drive uses a crank mechanism. Cutting tools for the planer operation are usually tipped with high-speed steel, cast alloy, or carbide inserts. shaper. The cutting speed is changed by controlling the throttle valve which controls the flow of oil. Horizontal feed rates of up to approximately 0.170. The cutting stroke of the planer is achieved by moving the work past a stationary tool bit. 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. Figures below show diagrams of both shaper drive mechanisms. 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). 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 High-speed steel or cast alloys are commonly used in heavy roughing cuts and carbides for secondary roughing and finishing. The forward and backward motion is obtained by “Quick Return Mechanism”. It's principal components are shown here.Cincinnati Machine. These shapers use from 2- to 5-hp motors to drive the head and the automatic feed. Tooling is simple, and shapers do not always require operator attention while cutting.

Typical work would be machine beds and columns, marine diesel engine blocks, and bending plates for sheet-metal work. 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. The drive may be 15 hp on the smaller planers, and 100 hp or more on the larger models. Worms & Worm wheels cannot be generated on gear shapers. 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. Although both the planer and the shaper are able to machine flat surfaces, there is little overlapping in their application. The workpiece mounts on a rigid, box-shaped table in front of the machine. The width and height are usually, but not always, the same. Open the door, and you will see the screw that adjust this. The maximum is at the center of the stroke. The reverse stroke is made faster than the power stroke because of the smaller area in the return side of the cylinder, if a constant volume pump is used.
