Experimental Investigation on Effects of Tool Condition on Processing Quality during Broaching 26NiCrMoV145 Supperalloy

Abstract:

Reasonable tool condition has crucial importance to prevent tool malfunction such as abnormal wear, chipping and cutting teech breakage when broaching expensive components i.e. gas turbine engines disks. This paper proposes a broaching simulation test method of using customized single tooth groove tools with a variety of rake angle and clearance angle to simulate broaching processing at shaper machine under different cutting depth. The effects of tool condition and cutting depth on cutting forces, surface roughness analyzed by Response Surface Methodology and surface morphology of machined surface were discussed, which revealed that the changes of cutting depth play a dominate role in processing quality, followed by tool rake angle, and tool clearance is subordinate. Good tool edge strength should be assured from prevent shock and vibration during the selection of tool condition.
