Cutting Force Estimation in a Micromilling Process

Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2010
The cutting force estimation of a micro-mill in a milling process was investigated in the present study. As the micro-machining cutting force is so small, the force is difficult to measure using the traditional load cell and therefore cutting force estimation in a milling process was considered.

Cutting force estimation in sculptured surface milling

International Journal of Machine Tools and Manufacture, 2004
Abstract Cutting force milling models developed up to now are mostly used for planar milling using end-mills. Only a reduced number of models applying ball-end mills have been developed. Furthermore these models usually only consider horizontal surface machining, even though the main application of ball-end mills is sculptured surface machining. This

Radial immersion angle estimation using cutting force and predetermined cutting force ratio in face milling

International Journal of Machine Tools and Manufacture, 2002
Radial immersion ratio is an important factor to determine the threshold for tool conditioning monitoring and automatic force regulation in face milling. In this paper, a method of on-line estimation of the radial immersion angle using cutting force is presented. When a tooth finishes sweeping, a sudden drop of cutting force occurs.

Estimation of cutting forces in micromilling through the determination of specific cutting pressures

Journal of Materials Processing Technology, 2007
Abstract In this paper a new model for the estimation of cutting forces in micromilling based on specific cutting pressure is presented. 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.

Compensation of friction and force ripples in the estimation of cutting forces by neural networks

Measurement: Journal of the International Measurement Confederation, 2018
Abstract Estimated cutting forces are usually mixed up with disturbing forces such as friction and need to be compensated. In common compensation methods, such forces are firstly recorded along machining contours under air-cutting conditions. Then, recorded disturbing forces are recalled for the compensation during the main machining process.

Estimation of the specific cutting pressures for mechanistic cutting force models

International Journal of Machine Tools and Manufacture, 2001
This paper presents a new method for the estimation of specific cutting pressures for mechanistic cutting force models for the face milling process. Traditional methods for the estimation of specific cutting pressures require calibration tests using a single cutting insert on a workpiece which has no surface discontinuities.

CORRELATION-BASED ESTIMATION OF CUTTING FORCE COEFFICIENTS FOR BALL-END MILLING

Machining Science and Technology, 2012
This article presents a methodology to estimate cutting force coefficients based on the least squares approximation using correlation factor between the estimated and measured cutting forces in order to determine the corresponding tool angular position.
