Kinematics Error Compensation for a Surface Measurement Probe on an Ultra-Precision Turning Machine

Methods of In-Process On-Machine Auto-Inspection of Dimensional Error and Auto-Compensation of Tool Wear for Precision Turning

The purpose of this study is mainly to develop an information and communication technology (ICT)-based intelligent dimension inspection and tool wear compensation method for precision tuning. With the use of vibration signal processing/characteristics analysis technology combined with ICT, statistical analysis, and diagnosis algorithms, the method can be used to proceed with an on-line dimensio...

Profile Generation for Brittle Materials by Using Ultra-precision Lathe with On-machine Measurement System

Error Compensation System for Joints, Links and Machine Frame of Parallel Kinematics Machines

This paper describes error compensation methods for parallel kinematics machines (PKMs). First, joint errors and link deformations caused by external forces and heat are discussed. Because a linear scale unit is connected to each spherical joint located at both ends of an extensible limb through two rods, the scale unit can measure not only displacement of the prismatic joint but also the limb’...

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

Surface Generation in Ultra Precision Single Point Diamond Turning of Aluminum

INTRODUCTION Ultra precision single point diamond turning is a very promising tool based manufacturing technology because of its reliability, productivity and wide range of applications. However, with the reduction in cutting dimensions compared to traditional precision machining, the process physics differs substantially. This is largely because of size effects and increased surface finish exp...
