Chatter control in machinery significantly affects the product surface quality. The variable helix angle tool is a technique that gives the tool an angle with a different pitch angle to the tool axial axis. The variable helix angle tool provides a solution for solving time delay as a cause of the emergence of chatter. In this research, an evaluation of the two tool conditions with normal helix angle (400) and variable helix angle (400/420) was performed on the cutting parameters (depth of cut; spindle speed, feed rate). The results obtained by performance evaluation were tools with variable helix angles capable of producing significantly better surface roughness quality compared to normal helix angle tools. © Published under licence by IOP Publishing Ltd.
