This creates a very strong, rigid structure that will handle heavy loads without deflection. chart such as the one shown in table 9-1. cut. They both make the same types of cuts. To vary the position, you use the lock levers on the top of the ram. In shaper, feed is normally given to the work piece and can be automatic or manual. However, it is a production-- type machine for certain types of work. 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. Cut Settings. It cuts the metal in one stroke in back motion or in froth motion and the remaining one is useless. Toolhead: The toolhead is fastened to the ram on a circular plate so that it can be rotated for making angular cuts. Clapper Box: The clapper box is needed because the cutter drags over the work on the return stroke. The return is governed by a quick return mechanism. The cutting speed of a shaper is the speed at which the metal is removed by the cutting tool in one minute. Worktables on planers and shapers are constructed with T-slots to hold and clamp parts that are to be machined. 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. The stroke per minute available on a shaper will vary according to the size of the shaper. Tooling is simple, and shapers do not always require operator attention while cutting. Determine the time to machine the component with width of 150 mm. Open-sided Planers: Open-sided planers have the housing on one side only. 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… 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. The table may be supported at the outer end. The Shaper The horizontal shaper is the most common type. The earlier illustration shows how the tools are supported both above and on the sides, and their adjustment for angle cuts. On the planer the tool is fed into the work; on the shaper the work is usually fed across the tool. The forward and backward motion is obtained by “Quick Return Mechanism”. 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. Cutting Feed: Feed per stroke on a shaper is comparable to the feed per revolution on a lathe. Atlas started manufacturing the 7 inch shaper in 1937 which sold for $198.00. Shaper machine is used to produce horizontal, vertical or inclined flat surfaces. [2] However, Roe (1916) credits James Nasmyth with the invention of the shaper in 1836. Automatic Table Feeding Mechanism of Shaper. As the ram reciprocates, the tool cuts the material during its forward stroke. 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. In a standard shaper, cutting of material takes place during the forward stroke of the ram and the return stroke remains idle. The cutting speed remains nearly constant through the full stroke. The planer handles work weighing up to several tons. The shaper is a relatively simple machine. It is then necessary to compute the strokes per minute since that is how the shaper speed is controlled. 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. 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. Description of Parts of Shaping Machine with its Functions Cutting Feed: Feed per stroke on a shaper is comparable to the feed per revolution on a lathe. What type of material are you cutting, how much depth, what kind of cut (standard flat, dovetail, etc.) It is used to shape the metal or make flat surfaces, making grooves and slots. However, the return stroke is made at up to twice speed of the cutting stroke. Adding axes of motion to a shaper can yield helical toolpaths, as also done in helical planing. 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. Cutting Speed and Feed: The cutting speed of the hydraulic shaper is infinitely variable by means of hydraulic controls, as is the cross feed. Ans: choosing 28 strokes/min, time=44.65min These shapers use 5- to 10-hp motors. Speed and feed on a hydraulic shaper are often controlled by simple dials. They differ greatly in construction and in the method of operation. The RPM of the bull gear becomes the strokes per minute (sometimes abbreviated SPM) of the shaper. 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. In a standard shaper, cutting of material takes place during the forward stroke of the ram and the return stroke remains idle. Cutting is done during the return stroke as the tool is set in a reversed direction to that of the standard shaper. If a rotary table is mounted on the regular table, a number of slots can be made at quite accurately spaced intervals. Table: The table is a heavy casting which carries the work past the cutting heads. The most common use is to machine straight, flat surfaces, but with ingenuity and some accessories a wide range of work can be done. 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. This has a tool post very similar to that used on the engine lathe. It was discontinued in the year of 1961. © 2021 Endeavor Business Media, LLC. 27. The Planer 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. Most planers have one flat and one double V-way, which allows for unequal bed and platen expansions. The vise can be equipped with all standard top jaws with tongue and groove (KTR, KTR-H) from Schunk’s extensive chuck jaw program. 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. 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. 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. Both the shaper and the planer are single-point tools that cut only in straight lines:The shaper handles relatively small work. High-speed steel or cast alloys are commonly used in heavy roughing cuts and carbides for secondary roughing and finishing. 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. just as in the lathe, but in a vertical plane. 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. Although both the planer and the shaper are able to machine flat surfaces, there is little overlapping in their application. 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. Grab … shaper. [3] Shapers were very common in industrial production from the mid-19th century through the mid-20th. The depth of the cut is adjusted by moving the tool downwards towards the work piece. All rights reserved. The ram reciprocates and the cutting tool, held in the tool holder, moves forwards and backwards over the work piece. 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. Its compact and square design ensures optimal accessibility and enables a stroke of 6 mm per jaw. The shaper handles relatively small work. Reciprocating movements over the work piece results in forward and backward strokes. 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 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. It is expressed in mm/double stroke or simply mm/stroke because no cutting is done in return stroke This is close to a 3:2 ratio.
