Consider the following statements about planning:1. Larger workpieces ...
The correct answer is option 'D' - 1, 2, and 4.
Let's analyze each statement:
1. Larger workpieces can be machined: Planning is a machining process that involves removing material from a workpiece using a cutting tool. One advantage of planning is that it allows for the machining of larger workpieces compared to other machining processes like milling. This is because the workpiece is stationary, and the cutting tool moves over it. Therefore, statement 1 is correct.
2. More number of cutting tools can be used simultaneously: In planning, multiple cutting tools can be mounted on the toolhead and used simultaneously to machine the workpiece. This allows for increased efficiency and productivity as multiple surfaces can be machined simultaneously. Therefore, statement 2 is correct.
3. It works on the principle of slotted link mechanism: This statement is incorrect. Planning does not work on the principle of a slotted link mechanism. The slotted link mechanism is a type of mechanism used in machines for converting rotary motion into reciprocating motion or vice versa. Planning, on the other hand, uses a single-point cutting tool that moves in a straight line to remove material from the workpiece. Therefore, statement 3 is incorrect.
4. It produces more accurate surfaces: Planning is known for its ability to produce accurate and precise surfaces on the workpiece. The cutting tool can be adjusted to achieve the desired depth of cut, and the feed rate can be controlled to ensure uniform material removal. This results in smooth and accurate surfaces. Therefore, statement 4 is correct.
In conclusion, statements 1, 2, and 4 are correct, while statement 3 is incorrect.
