7.10 CONTOUR TRAIN (Cycle 25,
DIN/ISO: G125)
Cycle run
In conjunction with Cycle 14 CONTOUR GEOMETRY, 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 inside corners of
the contour can be reworked using the feature for automatic
identification of residual material.
 The contour can be machined throughout by up-cut or by climb
milling. The type of milling even remains effective when contours
are mirrored in one axis.
 The tool can traverse back and forth for milling in several infeeds
(reciprocating plunge-cut): This results in faster machining.
 Allowance values can be entered in order to perform repeated
rough-milling and finish-milling operations.
 Cycle 270 CONTOUR TRAIN DATA provides an easy way to define
the behavior of Cycle 25.
