Abstract
Despite the applicability in machining processes, current polygonal holes are manufactured by stamping but not by cutting. This will raise the required components’ price and influence the machining procedure for mechanical products. This paper proposes a concept method for machining parts with polygonal cross-section holes by cutting. Based on the motion of gear transmission in constructing Epitrochoid curves, a unique mechanism to control the position of straight groove drills bit to machines polygons’ holes is presented. Numerical calculations have been built to allow the detection of optimized machining parameters. Results from the study show that polygons holes machined from the new method can be applied in machining multiple types of polygonal without replacing cutting bits.
