Question

in a point to point type of NC system,_____________
1. control of only position of tool is critical
2.control of only path of tool is critical
3.control of both position and path of tool is critical
4. neither position and path of tool is critical​

Answer 1

Answer:

3.conyrol of both position and path of tool is critical

Answer 2

(3) Control of both position and path tool is critical in a point to pint type of NC system.

Definition of point to point type;

When the end point movement between the path is not important called as point to point type control system.

Reference of point to point in a NC system;

• They are two types of division between the Numerical control system;

1. Point to point
2. Continuous path

• Point to point systems are used in machines in straight line milling operations and hole machining.
• Continuous path are more complex and require the help of computer. They are usually closed loop.
• According to the NC system the control of only position of tool is essential.
• In the point to point the one axis tool is sufficient for the numerical control system. By controlling the both position and path tool will be critical.

Therefore the one axis in the point to point type is sufficient and the control of any one position will benefit and work accordingly to the system.
