Influence of the Estimation of Cutting Force Coefficients in Micromilling

This paper presents a new model for the estimation of cutting forces in micromilling based on specific cutting pressure. The proposed model includes three parameters which allow to control the entry of the cutter in the workpiece and which consider also the errors in the radial position of the cutting edges of the tool. The presented model is orientated to adaptive control in the micromilling p...

Investigation of Cutting Forces Superalloy Inconel 718

Since the cutting tools used in machining process of super alloys are subjected to high cutting forces, accordingly tools life is reduced, therefore improvement in alloys machining and reducing cutting forces to achieve longer tools life is an essential necessity. In this research, the effect of changes in feed rate on cutting forces in machining process of nickel based super alloys is investig...

Estimating Cutting Forces in Micromilling by Input Estimation from Closed-Loop Data

Estimation of cutting forces in micromilling from the signals of a spindle with Active Magnetic Bearings (AMB) is treated as an input estimation problem. For the closed-loop AMB system, a minimum mean square error input estimator with an adjustable delay is derived. This filter is based on the Wiener filter, where the unknown input is treated as white noise filtered by known dynamics and the co...

Machining with Minimal Cutting Fluid

The purpose of cutting fluid in a machining operation is to cool the workpiece, reduce friction, and wash away the chips. The cutting fluid contributes significantly toward machining cost and also possesses environmental threats. In the past, there have been some attempts to minimize the amount of cutting fluid in machining. This chapter reviews some prominent ways to minimize the application o...
