Settings for edge machining (edge_machining.*)
 | This functionality is available as of Release V2.11.2009.12. It is enabled in the start-up list ([STUP]) for each CNC channel as follows (as an example): |
Depending on the machining technology it may be necessary to control the machining process especially on sharp contours (edges). In the case of a sharp edge (defined by the angle difference between two contour elements), the path velocity at the edge is modified depending on pre-defined parameters. In addition, three signals are generated, derived from path velocity. These signals are supplied to the PLC interface (see HLI documentation, Status information of a channel -> Edge functions -> Signal_1, Signal_2, Signal_3). Linear or circular blocks can be programmed as contour elements. No check is made here whether they are inner or outer contours. If the functions ‘Insert chamfers and roundings (G301/G302)’ or tool radius compensation (G41/G42) are active, additional contour elements can be generated. They then result in a different bend angle than exists between the two original contour elements.
The following parameters are required to set the edge machining function:
