In the slotter machine, a quick return mechanism is used to drive the ram for cutting the metals from the workpiece. It is called a quick return mechanism because here the time taken by the ram in return stroke is less as compared with the forward stroke i.e. return stroke move quicker than the forward stroke.
Which type of mechanism is used in Slotter machine Mcq?
Explanation: Column carries table elevating mechanism. Column act housing for an operating mechanism in slotting machine and hence it is made of hard material.
What is the mechanism used in shaping machine?
Shaping machines uses quick return mechanism. That is an inversion of slider crank mechanism.
What is the working principle of Slotter?
The working of a slotter machine:
The ram is connected to the crank and the crank is connected to the gears. This allows the increase or decrease of the gear speed and take effect on the rotation of crank speed. It also allows the ram to move up and down.
Which mechanism is used for automatic table feed in shaper machine?
The automatic feed mechanism of the table is very simple. This is done by rotating a ratchet wheel, mounted at the crossfeed screw. This enables a corresponding equal rotation of the crossfeed screw after each stroke.

What is crank slotted mechanism in shaper machine?
The crank and slotted quick return mechanism was invented by Whitworth in the 1800s. It played an active role in increasing productivity by reducing cutting times in shaping machines. As a quick return mechanism it finds applications in various fields.
What is quick return mechanism in shaper machine?
A quick-return mechanism is a subclass of a slider-crank linkage, with an offset crank. Quick return is a common feature of tools in which the action is performed in only one direction of the stroke, such as shapers and powered saws, because it allows less time to be spent on returning the tool to its initial position.
How many operations can a slotter machine perform?
Only one tool is used for machining. It can machine only one surface at a time. It can machine three surfaces at a time. Same as a shaper.
Which angle is provided in Slotter tool?
The clearance angle (COG in Figure 17-10) should be 4° or 5°, and the rake angle (BOF in Figure 17-10) should be 10° or 12°. When the cutting tool is clamped to the end of the ram in a horizontal position, the clearance and rake angles are measured in the same manner as for planer tools.
Which of the following is used to obtain rotary movement of Slotter?
Worm and worm wheel mechanism mechanisms is used to obtain rotary movement of slotter table.
What are the different types of mechanism used in shaper?
- Crank and slotted link mechanism.
- Whitworth's quick mechanism.
- Hydraulic shaper mechanism.
- Automatic table feed mechanism.
What are the 3 main types of mechanisms used to generate the ram motion?
There are three principal types of actuators: electric, pneumatic, and hydraulic. Read more here.
Is used in shaper machine?
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 ram is typically actuated by a mechanical crank inside the column, though hydraulically actuated shapers are increasingly used.
Which type of mechanism is used in shaper machine 1 point?
It uses a crank mechanism to convert the circular motion of the bull gear into reciprocating motion of the ram. The ram carries a tool head at its end & provides the cutting action. In these types of shaper machines, the ram is reciprocating. The ram is affecting due to reciprocating motion with the rack and pinion.
Which one of the following operations Cannot be performed on Slotter?
Explanation: Square thread cutting operations cannot be performed on slotter.
Where is quick return mechanism used?
A quick return mechanism is an apparatus that converts circular motion into reciprocating motion in presses and shaping machines, which are utilized to shape stocks of metal into flat surfaces. This mechanism is mostly used in shaping machines, slotting machines and in rotary internal combustion engines.
What are the different types of Slotter?
- Puncher Slotter.
- Precision Tool Room slotter.
- General Production Slotter.
- Keyseater Slotter.
Which type of surface is produced by turning operation in lathe machine?
Explanation: Cylindrical surface is produced by turning operation in lathe machine. This turning can be done on the external surface. Boring is a type of turning which is performed in the internal surface.
Which tool is used on broaching machine?
Broaching is a machining process that uses a toothed tool, called a broach, to remove material. There are two main types of broaching: linear and rotary. In linear broaching, which is the more common process, the broach is run linearly against a surface of the workpiece to effect the cut.
What is the use of Slotter machine?
Slotting machine is used for cutting grooves, keys and slotes of various shapes making regular and irregular surfaces both internal and external cutting internal and external gears and profiles. Slotter machine can be used on any type of work where vertical tool movement is considered essential and advantageous.
Who invented Slotter machine?
A slotter machine is one the oldest machine tool that exist, which was invented for BRUNEL. It is much similar to the vertical shaper machines as the ram carrying the slotting tool reciprocates in a vertical guide-way of the machine. This machine can produce flat and contour surfaces, slots and internal grooves.
What are the specification of a slotter machine?
Specifications of 400 mm slotter are given below: Highest distance as of clamping surface of table to lower end of ram guideways 600 mm. Highest space as of tool to clamping surface of table 870 mm. Distance from seating surface of tool to housing 890.
What is the use of Geneva mechanism?
Geneva mechanism, also called Geneva Stop, one of the most commonly used devices for producing intermittent rotary motion, characterized by alternate periods of motion and rest with no reversal in direction. It is also used for indexing (i.e., rotating a shaft through a prescribed angle).
What are the main types of quick return motion mechanism used in shaper?
- Whitworth Quick Return mechanism.
- Crank and Slotted Link Mechanism and.
- Hydraulic Drive.
What is single slider crank mechanism?
A single slider crank chain is a modification of the basic four bar chain. It consist of one sliding pair and three turning pairs. It is, usually, found in reciprocating steam engine mechanism. This type of mechanism converts rotary motion into reciprocating motion and vice versa.
