To solve the problems that the low rigidity thin-walled part is easy to deform in NC milling process and some parts of the complex surface is difficult to process, this paper points out the measures for increasing accuracy of thin-walled NC machining process from the selection of material and blank, the choice of machine tool, the determination and optimization of the clamping method, the choic...

Industrial robots are used in a great variety of applications for handling, welding and milling operations. They represent a cost-saving and flexible alternative for machining applications. A reduced pose and path accuracy, especially under process force load due to the high mechanical compliance, restrict the use of industrial robots for further machining applications. In this paper a method i...

This paper presents the optimization of high speed milling process parameters with respect to the surface roughness of samples and the study of the Taguchi design application to surface quality in a CNC end milling operation. The Taguchi design is an efficient and effective experimental method in which a response variable can be optimized given various control factors using fewer resources than...

The application of variable helical end mills to the milling titanium alloys can suppress regeneration effect during machining process and ensure stability milling. However, due their special geometry, characteristics are also different. In this paper, alloy with a helix mill is taken as research object, force, deeply studied. Firstly, feed per tooth cutting thickness model were established, fo...

In this paper, the straight flute end-milling cutter used for machining of Al-Si-Mg-Fe alloy work pieces was investigated. The machining processes could induce residual stresses that enhance greatly the performance of the machined component. Machining residual stresses correlate very closely with the cutting parameters. In the experiments, the residual stress on the surface of workpiece was mea...

Machinability aspect is of considerable importance for efficient process planning in manufacturing. Machinability of an engineering material may be evaluated in terms of the process output variables like material removal rate, processed surface finish, cutting forces, tool life, specific power consumption, etc. In this paper, graph theoretic approach (GTA) is proposed to evaluate the cutting fo...
