Questions and Answers

In incremental programming, what does a 'Y minus' (Y-) command do?

  • Cause the cutting tool to be located toward the column (correct)
  • Cause the cutting tool to be located away from the column
  • Cause the cutting tool to be located to the right of the last point
  • Cause the cutting tool to be located to the left of the last point

    • What type of machine tool is used as an example to explain command codes in the incremental system?
