which stroke is cutting stroke in shaper

The shaper ram also can be driven in this manner, but many times a quick-return link mechanism is used. ... many strokes for the 4-inch cut as it does for the 12-inch. Acceleration and deceleration of the table takes place in a short distance of travel and does not influence the time to machine. Grab … The vise may also have a swivel base so that cuts may be made at an angle. 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. Although both the planer and the shaper are able to machine flat surfaces, there is little overlapping in their application. The stroke per minute available on a shaper will vary according to the size of the shaper. 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. They are fed by power in either a vertical or a crosswise direction. Tools used in shaper and planer work are single point as used on a lathe, but are heavier in construction. The ram reciprocates and the cutting tool, held in the tool holder, moves forwards and backwards over the work piece. 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). In shaper, Ram holding the tool reciprocates in a horizontal axis whereas, in slotter, the ram holding the tool reciprocates in a vertical axis. Crossrail: The crossrail is also a heavy box, or similar construction. It was discontinued in the year of 1961. Column: The column supports the ram and the rails for the saddle. The gearing of hydraulic cylinders for driving the table is housed under the bed. The depth of the cut is adjusted by moving the tool downwards towards the work piece. Drive Mechanisms Both the shaper and the planer are single-point tools that cut only in straight lines. It is used to shape the metal or make flat surfaces, making grooves and slots. 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. The most frequently used type of planer is the double-housing planer. 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. The larger shapers will have lower speeds. Clapper Box: The clapper box is needed because the cutter drags over the work on the return stroke. But in slotter machines, the direction of cutting stroke is vertical with slower than the return stroke. It can take heavy cuts with 'less vibration and strain on the work table. The toolhead can also be moved up or down by its hand crank for precise depth adjustments. Finish would also depend on the nose radius of the cutting tool. Cutting angles for tools depend on the tool used and the workpiece material. 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. This flexibility, coupled with the use of specialized cutters and tool holders, enable the operator to cut internal and external gear teeth. It is used fairly often in the toolroom or for machining one or two pieces for prototype work. 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. Ans: choosing 28 strokes/min, time=44.65min The vise can be equipped with all standard top jaws with tongue and groove (KTR, KTR-H) from Schunk’s extensive chuck jaw program. 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 motor driving the pinion gear is the reversible type with variable speed. Since planers make heavy cuts, their tools are much larger. Know your Shaper – Details on the Atlas Shaper by Sam Brown; Contour Cutting with the Atlas Shaper by Sam Brown; History. Its cut is analogous to that of a lathe, except that it is (archetypally) linear instead of helical. The horizontal shaper is the most common type. 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. 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. The cutting speed of a shaper is the speed at which the metal is removed by the cutting tool in one minute. The ram is typically actuated by a mechanical crank inside the column, though hydraulically actuated shapers are increasingly used. [2] However, Roe (1916) credits James Nasmyth with the invention of the shaper in 1836. The drive may be 15 hp on the smaller planers, and 100 hp or more on the larger models. Question: In Shaper Machine The Metal Cutting Can Be Done In The Following Stroke Select One: O A. It can machine any flat or angular surface, including grooves and slots, in medium and large sized workpieces. Cutting speeds are affected by the rigidity of the machine, how the work is held, tool, material, and the number of tools in operation. This specifies the approximate width of the table which ranges from 30" to 72". A planer makes the same types of cuts as a shaper. The work piece is rigidly held in a vice or clamped directly on the table. 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 starting point and the length of the stroke can be adjusted. Forward stroke is responsible for cutting action over the object and backward movement is responsible for restoring its position without any cutting action. A Brush that specifies how the Shape outline is painted. Comparison of Shapers and Planers The table has T-slots, both lengthwise and across, in which heavy bolts and clamps may be used. 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. 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. 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 just as in the lathe, but in a vertical plane. This return stroke is governed by a quick return mechanism. On the planer the work is moved against a stationary tool: on the shaper the tool moves across the work, which is stationary. 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. High-speed steel or cast alloys are commonly used in heavy roughing cuts and carbides for secondary roughing and finishing. The planer handles work weighing up to several tons. Speed is read directly in feet per minute and feed is read directly in decimal inches. 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. Worms & Worm wheels cannot be generated on gear shapers. Cut mode is the heart of Shaper Origin. Moving the tool bit attached to the ram makes the cutting stroke of the shaper. It is then necessary to compute the strokes per minute since that is how the shaper speed is controlled. 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. 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. Upward Direction B. Its compact and square design ensures optimal accessibility and enables a stroke of 6 mm per jaw. The tool-slide permits feeding the tool downwards to deepen a cut. The cutting stroke of the planer is achieved by moving the work past a stationary tool bit. The table may be supported at the outer end. Workholding: Workholding is frequently done in a vise.
