Influence of the Estimation of Cutting Force Coefficients in Micromilling
نویسندگان
چکیده
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 process so that variations in the cutting conditions during the machining process are easily treated by this model and taken into account in the control algorithms for the process optimization. The accuracy of the estimated parameters of the cutting force expression plays a vital role in the resulting cutting force. For this reason, the influence of the fitting of the cutting force coefficients is analyzed.

متن کاملPulsed Laser Assisted Micromilling for Die/Mold Manufacturing
Laser assisted machining is an alternative to conventional machining of hard and/or difficult-to-process materials which involves pre-heating of a focused area with a laser beam over the surface of the workpiece to cause localized thermal softening along the path of the cutting action. The main advantage that laser assisted machining has over conventional machining is the increased material rem...
