This is the reason why the name of the main program must not end with "_C" and a two-digitnumber. This is monitored by the cycles.For programs with residual machining, when specifying the name for the file, which includesthe updated blank contour, it must be ensured that this does not have the attached characters("_C" and double-digit number).For single-channel systems, cycles do not extend the name for the programs to be generated.NoteG code programFor G code programs, the programs to be generated, which do not include any path data, aresaved in the directory in which the main program is located. In this case, it must be ensuredthat programs, which already exist in the directory and which have the same name as theprograms to be generated, are overwritten.Input simpleFor simple machining operations, you have the option to reduce the wide variety of parametersto the most important parameters using the "Input" selection field. In this "Input simple" mode,the hidden parameters are allocated a fixed value that cannot be adjusted.Machine manufacturerVarious defined values can be pre-assigned using setting data.Please observe the information provided by the machine manufacturer.If the workpiece programming requires it, you can display and change all of the parametersusing "Input complete".Machining typeYou can freely select the machining type (roughing, finishing or complete machining - roughing+ finishing). During contour roughing, parallel cuts of maximum programmed infeed depth arecreated. Roughing is performed to the programmed allowance.You can also specify a compensation allowance U1 for finishing operations, which allows youto either finish several times (positive allowance) or to shrink the contour (negative allowance).Finishing is performed in the same direction as roughing.Procedure1.
