Circular path CT

Application

You use the circular path function CT to program a circular path that connects tangentially to the previously programmed contour element.

Requirement

  • Previous contour element programmed
  • Before you can program a circular path with CT you must program a contour element to which the circular path can connect tangentially. This requires at least two NC blocks.

Description of function

8H000_51

The control moves the tool on a circular path, with a tangential connection, from the current position to the defined end point. The starting point is the end point of the preceding NC block. You can use at most two axes to define the new end point.

When contour elements uniformly merge into another without kinks, then this transition is referred to as tangential.

Programming a circular path CT

  1. To program a circular path with CT:
Ct

  1. Select CT
  2. Define the coordinates of the end point
  3. Select radius compensation, if necessary
  4. Define the feed rate, if necessary
  5. Define a miscellaneous function, if necessary

Note

Both coordinates of the contour element must lie in the same plane as the coordinates of the circular path.
