Rounding RND

Application

The RND rounding arc function allows you to insert a rounding arc between two straight lines. The rounding arc is based on the intersection that you have programmed with the straight lines.

Requirements

  • Path functions before and after the rounding arc
  • Identical tool compensation before and after the rounding arc
  • Rounding is machinable with the current tool

Description of function

You program the rounding arc between two path functions. The circular arc connects tangentially to the previous and subsequent contour element. The control does not traverse to the intersection.

If you program a feed rate in the RND block, then this feed rate is in effect only while cutting the rounding arc.
