No automatic leads are generated and no CRC codes are output. The default perpendicular lead length is 0.5 * cutter radius. The perpendicular lead length is 1.5 * cutter radius. CRC is applied (G41/G42) on the first linear lead in move and cancelled (G40) on the last linear lead out move. A Radius Compensation factor of 1.5 is the default.
The length of the automatically generated move is specified in the code generator machine section. It can be overridden by specifying a perpendicular value in the cycle lead parameters. This move is generated automatically by Edgecam when Centerline or Geometry is specified. Most controllers expect CRC to be applied on a perpendicular linear approach move. When applying and removing cutter radius compensation (CRC) you must follow the rules of the machine tool and specify your lead moves accordingly. Applying and Removing Cutter Compensation As a further precaution you can specify a minimum radius, as explained below in the section Possible Errors with Controller Compensation.ĬRC Register – This is the machine tool controller CRC offset register.
This is to avoid controller problems, and problems with the machined part not
