CONTOUR TRAIN (Cycle 25, DIN/ISO:

In conjunction with Cycle 14 CONTOUR, this cycle facilitates the

machining of open and closed contours.

Cycle 25 CONTOUR TRAIN offers considerable advantages over

machining a contour using positioning blocks:

The TNC monitors the operation to prevent undercuts and

surface blemishes. It is recommended that you run a graphic

simulation of the contour before execution.

If the radius of the selected tool is too large, the corners of the

contour may have to be reworked.

The contour can be machined throughout by up-cut or by climb

milling. The type of milling even remains effective when the

contours are mirrored.

The tool can traverse back and forth for milling in several

infeeds: This results in faster machining.

Allowance values can be entered in order to perform repeated

rough-milling and finish-milling operations.
