Question

Match list I with list II and select the correct answer using the code given:

• A. 1 – iii, 2 – ii, 3 – i, 4 – iv
• B. 1 – ii, 2 – iii, 3 – iv, 4 – i
• C. 1 – iv, 2 – i, 3 – ii, 4 – iii
• D. 1 – iii, 2 – i, 3 – iv, 4 – ii

Hint:

Understanding CNC programming and machine control languages enhances the ability to optimize machining operations and troubleshoot issues effectively.

Answer 1

The Correct Option is C

Matching each CNC programming concept to its function.
1. Interpolation, especially in CNC, refers to the method of contouring, where the machine paths between points in a smooth, defined manner.
2. Parity check relates to tape preparation, as it involves error-checking mechanisms in data storage or transmission.
3. Preparatory function in CNC programming usually refers to canned cycles like those used for drilling.
4. Point to point control is fundamental in drilling operations, where the machine moves from one point to another without necessarily considering the path in between.
