Centerless grinding for notched workpieces.

Realisation of grinding-hardening in workpieces of curved surfaces—Part 1 Plunge cylindrical grinding

This paper investigates the feasibility to achieve grinding-hardening in a plunge cylindrical grinding process. To understand the mechanisms, a temperature-dependent finite element heat transfer model incorporating a triangular moving heat source was developed to describe the temperature field, thus to predict the thickness of the grinding-hardened layer. The analysis carried out included the v...

Fabrication of Microscale Tungsten Carbide Workpiece by New Centerless Grinding Method

Planning for Manufacturing Workpieces by Storing , Indexing

Planning for manufacturing workpieces is a complex task that requires the interaction of a domain-speciic reasoner and a generic planning mechanism. In this paper we present an architecture for organizing the case base that is based on the information provided by a generic problem solver. A retrieval procedure is then presented that uses the information provided by the domain-speciic reasoner i...

Computer Vision System for Manufacturing of Micro Workpieces

Two neural network based vision subsystems for image recognition in micromechanics were developed. One subsystem is for shape recognition and another subsystem is for texture recognition. Information about shape and texture of the micro workpiece can be used to improve precision of both assembly and manufacturing processes. The proposed subsystems were tested off-line in two tasks. In the task ...

Neural Network Based Vision System for Micro Workpieces Manufacturing

A neural network based vision system for micro workpieces manufacturing is developing. The system has to recognize the shapes of the micro workpieces and to give the information for correction of the workpieces manufacturing process. The system prototype was proved off-line on the task of 3 mm screw shape recognition. The shape distortions were made with the incorrect position of the cutter in ...
