Study of the Effect of Progressive Feed Rate on the Cutting Force in CNC End Milling of AISI 1045 Steel

摘要

This study focuses on the effect of cutting parameters on the cutting force in an end milling operation. Spindle speed, feed rate and depth of cut are the major factors which influence the cutting force. A concept of progressive feed rate, which is unlike the conventional constant feed rate, is introduced. AISI 1045 steel has been chosen as it is widely used in manufacturing. Design of Experiments (DOE) technique was adopted to conduct the experiments. Experiments were conducted and the mean cutting force was measured. A statistical model was developed using Design Expert software. The predicted values were compared with the experimental values and were found to be in close agreement. ANOVA technique was used to analyse the data for checking the model adequacy and for process optimization.
