Example workpiece milled by 3 to 3+2 axes

Using an example shaft-shaped workpiece, the programming is analyzed with 3-, 3+1- and 3+2-
axis. The procedure and results of the different milling operations are shown based on short
program excerpts.
Workflow start program, roughing and semi-finishing
For machining, a start program was created in each case which calls up the geometry programs.
This is identical for all four variants. The programs for the roughing and semi-finishing are the
same for the three workpieces. The differences are only to be found in the finishing programs.
The distance between the individual milling paths in the finishing programs has been set to be
relatively large so that the uniformity of the individual paths can be evaluated more accurately
and errors can be seen.
