Our main focus is to give our readers quality notes directly from the Professors, and Well Experienced Mechanical Engineers who already completed their education. The working principle of shaper machine is as follows: Shaping is the operation of removing a layer of material from the flat surface of the workpiece using a reciprocating single-point cutting tool. The horizontal shaper is generally used for the production of key-ways, flat surfaces, external grooves, etc. In current industrial practice, shapers have been largely superseded by other machine tools (especially of the CNC type), including milling machines, grinding machines, and broaching machines.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 rocker arm swings about the screw C, and at its upper end carries a spring-loaded pawl, as shown. Other machines such as milling machines are much more expensive and are more suited to removing smaller amounts of metal, very accurately. He also holds the position of Assistant Professor at Sreenidhi Institute of Science and Technology. Shaper Machine is used to remove the material from the surface of the workpiece by the usage of reciprocating single-point cutting tools basically on horizontal, vertical, and Inclined surfaces. 3. Saddle is mounted on the cross rail and its cross wise movement can be controlled by the crossfeed screw. So this is the detailed explanation of Shaper Machine. LITERATURE REVIEW [1]R M Lathe et.al., Investigated that conventional machining process consumes very high time and increases the labour cost, to overcome these problems and difficulties he used automated electric pneumatic devices and PLCs in shaper machine. To do this job, a mechanism called a clapper box with the Rocker ARM will be used to minimize the tool wear. Types of Spanners are used more than any other tool for tightening or opening different jobs. The workpiece can be movable in longitudinal, cross, and rotational movement. Whitworth mechanism A quick return mechanism is a mechanism which produces a reciprocal effect so that the system takes less time in the return stroke while comparing with forward stroke. Learn how your comment data is processed. The Piston-rod is bolted to the ram body. Letâs discuss the operations performed on it. The upper end of the rocker arm is forked and attached to the ram block by a pin. Share. It consists of a slotted disc, which carries a T-slot, as shown in the figure. 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 driving crank “CA” (link 3) rotates at a similar angular speed. The tool doesnot drag on the surface of the workpiece rather it can enables the toll to lift automatically.

This is just a simple Shaper Machine Mechanism. during the forward stroke) will be equal to the time taken by the driving crank to move from CA1 to CA2. Horizontal surfaces are machined by the use of horizontal cutting operation. If otherwise, the mechanism will be subjected to severe stress. The ram holding the tool gets the reciprocating movement. The left-hand end being smaller due to the presence of the piston rod. Castings are heavily ribbed internally giving perfect rigidity under maximum cutting conditions. Shaper Machine working principle, mechanism, Surface machining operation-, Shaping, Planing and Slotting Operations-. Crank and slotted link mechanism. The oil under high pressure is drawn from the reservoir. The major difference between a slotter machine and a shaper machine is that in a slotter the ram holding the tool reciprocates in the vertical axis. A tool head consists of apron and clapper box. Use DMU to see how it works ;) Sorry im not good at renderings. A quick return mechanism such as the one seen below is used where there is a need to convert rotary motion into reciprocating motion. It operates almost on the same principle as that of a shaper.. Lathe gives us a helical cut while the shaper gives us the ⦠TYPES OF QUICK RETURN MECHANISM. It is done by the mechanism contained within the column of the machine.

The table is not moved vertically but the feed is given to the tool by rotating the feed screw of the verticla slide. Against this, a finer feed is employed in finishing operations. The explanation for each part of shaper is as follows. Designed for machining flat surfaces on small sized jobs.If the size of the job is large, then planing isused. Shaper Machine Definition: The Shaper Machine is a reciprocating type of machine tool basically used to produce Horizontal, Vertical or Inclined flat surfaces by means of straight-line reciprocating single-point cutting tools similar to those which is used in lathe operation. It is used for machining of dies, punches, etc. In this post, you'll learn what is Jig Boring Machine. clapper box (b). Larger the said distance greater will be the feed and vice versa. The working of the Slotter machine is similar to the shaper machine do but the main difference between them is the Shaper machine works horizontally whereas Slotter machines … A small Scotch yoke mechanism has been thus devised to demonstrate the dual side machining time reduction in shaping machines. The applications of Shaper machine are as follows. The slider (link 4) connected to the crankpin at “A” moves along the slotted bar “PA” (link 1) which oscillates at a pivoted point D. The connecting rod PR carries the ram at R to which the cutting tool is fixed. The shaper mechanism should be so designed that it can allow the ram to move at a slower speed during the forward cutting stroke. 3. A shaper machine is one of the types of machine tool which uses the relative motion between the workpiece and the cutting tool. As the disc rotates the black slide moves forwards and backwards. It is used to shape the metal or make flat surfaces, making grooves and slots. Similarly, the time needed during the right to left movement of the ram (or during the idle or return stroke) will be equal to the time taken by the driving crank to move from CA2 to CA1. Working Mechanism of shaping machine is very simple but effective. idle stroke. When the driving crank CA moves from the point CA1 to CA2. Shaper Machine Definition: Shaper Machine is a production machine in which the single point cutting tools are attached and the workpiece is fixed and while moving forward the tool cuts the workpiece and in return, there is no cut on the workpiece and used for producing flat and angular surfaces. The slotted disc at its back carries a spur gear which is driven by the bull gear. 80 Downloads … Also, we have a great variety of pre-made project kits ⦠Aptitude Data Interpretation Verbal Reasoning Non Verbal Reasoning Verbal Ability Programming General Knowledge Puzzle.

Producing contour of concave/convex or a combination of these Working Principle : The job is rigidly fixed on the machine table.… The workpiece is fixed in the machine vice whereas the tool reciprocates on the workpiece by means of ram. This is the strongest part of any type of machine that has the ability to absorb the vibrations produced during machining. Letâs discuss in detail the types of shaper machine based on various parameters. In this project, a dual side shaper machine is designed with the help of quick return mechanism, the rotary motion of the motor is converted into linear motion of the tool which shapes the material mounted on the vice from both the side. Subscribe to our newsletter to get notify when we upload new posts. In this post, you'll learn What is Twist Drill and How it is used? In shaper, during working (cutting) stroke the tool block rests on the (a). one is a forward stroke or cutting stroke and the second is backward or return stroke. 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. Los productos de Shaper machine mechanism son los más populares de Western ⦠The shaper holds the single point cutting tool in ram and workpiece is fixed in the table. The mechanism used in Shaper Machine is Whitworth Quick Return Mechanism. The various types of shaping machines: Various types of shaping machines are classified into four such as motion type (driving mechanism), ram travel, table design, and the type of cutting stroke: Types of shaping machine base on driving mechanism: Crank type e.g. Slotter Machine. The speed of the bull gear may be changed by a different combination of gearing or by shifting the belt on the step cone pulley. It is used to shape the metal or make flat surfaces, making grooves and slots. Cutting Speed and Feed: The cutting speed of the hydraulic shaper is infinitely variable by means of hydraulic controls, as is the ⦠As the ram moves at a faster rate during return stroke, the time taken becomes less. It cuts the metal in one stroke in back motion or in froth motion and the remaining one is useless. Now when the driving crank moves from the point CA2 to CA1. This arrangement helps the power feed to operate in either direction, but the same should be set to operate during the return stroke only. If you have any questions about any topic you can ask in the comment section. Show more... Download files Like. The tool head is in the clapper box and the forward stroke is the cutting stroke and the backward stroke is the idle stroke. Use DMU to see how it works ;) Sorry im not good at renderings. It is essentially the same thing as of slotting machine. ï¶ The tool reciprocates over the work. Shaper machine 1. With the help of this linear motion, this device machine (cut) in a linear toolpath. Academic Resource. The various specifications of Shaper Machine depends upon the following. Here the work piece is fixed on the machine table and the cutting tool is placed on the work piece. The real capacity of shaper machines is to produce level surfaces in different planes. Hope you find it useful. Shaper machine works on the quick return mechanism. The mechanism of hydraulic shaper machine work as a motor that drives a hydraulic pump at a constant speed to deliver oil at a constant pressure to the line. In the case of Shaper Machine, the Workpiece is fixed in the machine vice and the Tool is under the Reciprocating motion of the ram and the material removal takes place from the surface of the workpiece in the form of layers. The work piece is held rigidly in a vice (or clamped directly on the table). It works on the principle of Whit worth Quick return motion mechanism. Thus the rotary motion of the bull gear is converted to reciprocating movement of the ram. This mechanism is known as quick return mechanism. This causes the connecting rod to reciprocate. 2. The cutting speed is changed by controlling the throttle valve which controls the flow of oil.
