Answer 1

The correct option is A: table position

Answer 2

Answer:

Correct option is:

a) Table position

Encoder is used to Sense and Controlling CNC machine tool, encoder is used to sense and control of Table position.

Explanation:

CNC machine:

The basic and advanced CNC functions are carried out by a specialized computer that is integrated into the control of a CNC machine.

• The computer supports program editing, program execution, control diagnostics, and additional program storage. Every time the program is changed on the tape and fed back into the CNC machine, it is very simple to change the program while the machine is operating as an NC machine.
• In CNC machine tools, the table position is sensed and controlled by the encoder.
• The encoder senses and controls the table position in CNC machine tools. In order to ensure that the machine tool is operating with the right speed and accuracy for the job, encoders are used in CNC machines to provide positional feedback while in use.
• The movement data is transformed into electrical signals by an encoder, an electromechanical position feedback device. To regulate the position and speed of machine axes, a CNC system needs motor drives.
