Cycle 270 CONTOUR TRAIN DATA
ISO programming
G270
Application
You can use this cycle to specify various properties of Cycle 25 CONTOUR TRAIN.
Notes
- This cycle can only be executed in the FUNCTION MODE MILL machining mode.
- Cycle 270 is DEF-active, which means that it takes effect as soon as it is defined in the NC program.
- If Cycle 270 is used, do not define any radius compensation in the contour subprogram.
- Define Cycle 270 before Cycle 25.

---|---|
Q390 Type of approach/departure? Definition of type of approach/departure: 1: Approach the contour tangentially on a circular arc 2: Approach the contour tangentially on a straight line 3: Approach the contour at a right angle 0 and 4: No approach or departure movement is performed. Input: 1, 2, 3 | |
Q391 Radius comp. (0=R0/1=RL/2=RR)? Definition of radius compensation: 0: Machine the defined contour without radius compensation 1: Machine the defined contour with compensation to the left 2: Machine the defined contour with compensation to the right Input: 0, 1, 2 | |
Q392 App. radius/dep. radius? Only in effect if a tangential approach on a circular path was selected (Q390 = 1). Radius of the approach/departure arc Input: 0...99999.9999 | |
Q393 Center angle? Only in effect if a tangential approach on a circular path was selected (Q390 = 1). Angular length of the approach arc Input: 0...99999.9999 | |
Q394 Distance from aux. point? Only in effect if a tangential approach on a straight line or a right-angle approach is selected (Q390 = 2 or Q390 = 3). Distance to the auxiliary point from which the tool will approach the contour. Input: 0...99999.9999 |
