Experimental Research on Drilling Force of Stainless Steel

Abstract

Accurate measurement of cutting force is an important means to study metal cutting process. In this paper, the measurement of drilling force for stainless steel is studied by means of drilling experiments. It is found that the measured values of drilling force are dispersive under the same conditions. The uniformity of mechanical properties of workpiece materials has a great influence on the value of drilling force. In calculating cutting force by finite element method, it is necessary to ensure that the performance parameters of the input material are consistent with the actual performance parameters of the workpiece.

Improved Method for Determining the Feed Influence on the Tangential Cutting Force During Re-drilling, Countersinking and Boring Based on the Small Sample Theory

“…In [18], a numerical and experimental study was carried out to investigate the effect of tool geometry on cutting forces, temperature distribution and residual stresses on the surface of stainless steel processing. Paper [19] is devoted to the determination of cutting forces during drilling, and verification by the finite element method is performed. In particular, it is noted in this work that cutting forces are not constant but have stochastic character.…”
