Continuous-Path Mode (G64, G641, G642, G643, G644) - Siemens SINUMERIK 840DE Programming Manual

Continuous-path mode (G64, G641, G642, G643, G644)

Function
In continuous-path mode, the contour is machined with a constant path velocity. The uniform
velocity also establishes better cutting conditions, improves the surface quality and reduces
the machining time.
Notice
In continuous-path mode, the programmed contour transitions are not approached exactly.
Sharp corners can be produced with G60 or G9. Continuous-path mode is interrupted by text
outputs with "MSG" and blocks, which trigger preprocessing, stop implicitly (e.g., access to
particular status data of machine ($A...)). The corresponding situation applies for the
auxiliary function outputs.
