We present a compliant end-effector that helps in cutting soft tissues and sensing the cutting forces. The design of the end-effector is such that it has an upper threshold on cutting forces to facilitate safe handling of tissue during automated cutting. This is shown with nonlinear finite element analysis and experimental results obtained by cutting inhomogeneous phantom tissue. The cutting fo...

this work presents an experimental investigation of the influence of the six important machining parameters (tool nose radius, tool rake angle, feed rate, cutting speed, cutting environment (dry, wet and cooled) and depth of cut) on surface roughness & material removal rate in the machining unidirectional glass fiber reinforced plastics (ud-gfrp) composite using carbide (k10) cutting tool durin...

Manufacturing processes are responsible for climate change due to the emissions produced as result of energy consumption. This paper analyzes the influence of the cutting conditions and the characteristics of cutting tools on the energy required in machining processes and the carbon dioxide equivalent (CO2-eq) emissions generated per material removed ratio (MRR) in an effort to define common cr...

The paper gives an analysis of acoustic-emission signals measured in the course of laser cutting of steels plates DC04 and X5CrNi18-10. Laser cutting is a process in which there can be a wide range of cutting parameters, but nevertheless cutting of plate products can be accomplished. Within the range of the parameters concerned, however, the quality of a cut edge can vary quite strongly; laser-...

Cutting tool geometry should be very much considered in micro-cutting because it has a significant effect on the topography and accuracy of the machined surface, particularly considering the uncut chip thickness is comparable to the cutting edge radius. The objective of this paper was to clarify the influence of the mechanism of the cutting tool geometry on the surface topography in the micro-m...

Chip formation during dry turning of Ti6Al4V alloy has been examined in association with dynamic cutting force measurements under different cutting speeds, feed rates and depths of cut. Both continuous and segmented chip formation processes were observed in one cut under conditions of low cutting speed and large feed rate. The slipping angle in the segmented chip was 551, which was higher than ...

This paper presents a Kalman filter designed for a cutting force measurement system. The cutting force measurement system is used to measure cutting forces for meso-milling applications. Due to the small magnitude of the cutting forces generated from the meso-milling process, the measurement results are easily distorted by the noise that exists in the measurement system. The object of the Kalma...

If we can evaluate a curve by means of a corner cutting algorithm, we call the corresponding system of functions a corner cutting system. We prove that corner cutting systems are always monotonicity preserving. We obtain weak sufficient conditions for corner cutting systems. Optimal stability properties and properties concerning the supports of the basis functions of corner cutting systems are ...
