Elimination of Thermal Damage in Form Grinding

Objective



Objectives and content

Form grinding is an important operation in the manufacture of many cutting tools and machine components. Improvements in production economy here is severely limited by thermal damage during production and consequent loss of quality.

The objective of this research project is to develop models and design procedures for high production economic form/profile grinding of high speed steel and carbon steels with assured product quality. For this we propose to combine three different special experimental techniques during form grinding. These will provide sufficient technical information relating temperature distribution, nature of the metallurgical damage and the rate of material removal with the state of the abrasive wheel and the form ground. Generation of thermal flux, heat-flow into the work piece and consequent damage will be mapped. These will be used to develop models for forces, temperature and damage level in form grinding.

Such models will then be synthesised into a set of verifiable algorithms for the estimation of optimum form grinding conditions with assured quality. This is expected to improve form grinding productivity appreciably. Such algorithms could be used to develop simple software for selecting grinding conditions, and as essential inputs for the design of adaptive control systems for the machine tools as well.
