Solution:
Which of the following terms correctly describes a machine tool having a dedicated computer to help prepare the program and control some or all of the operations of the machine tool?
Solution:
The tool of an NC machine has to move along a circular arc from (5, 5) to (10, 10) while performing an operation. The center of the arc is at (10, 5). Which one of the following NC tool path commands performs the above-mentioned operation?
Solution:
For a 3-axis CNC table, the slide along the vertical axis of the table is driven by a DC servo motor via a lead screw nut mechanism. The lead screw has a pitch of 5 mm. This lead screw is fitted with a relative (incremental) circular encoder. The basic length unit (BLU) of the slide along the vertical axis of the table is 0.005 mm. When the table moves along the vertical axis by 9 mm, the corresponding number of pulses generated by the encoder is:
