CAM systems Mill roughing routines Trochoidal vs. Tool Engagement Angle
There has been a lot of controversy around roughing routines and how good they work. The two most notable are Trochoidal Roughing and Tool Engagement Angle roughing.
Trochoidal roughing routine puts in hundreds or maybe thousands of loops in the roughing. The intent was to cut down on loading of the tool and give a smoother and maybe a faster rough tool path. This method of roughing still does not improve the swings in tool loads and is pretty much like the old ZIG ZAG and collapsing pocket routines.
Constant Cutter Engagement keeps only the percentage of the tool that is specified by the user engaged. Example .5 dia cutter 20% engaged would maintain a .1 depth of cut or less no matter what geometry that is encountered. There are several companies that are and have developed technology around the general idea of cutter engagement. This method has increased tool life by 2-5 times. This seems like the technology that is going to lead the way into high speed roughing and a great advance in productivity.
