CNC Machines are deployed in diverse range of manufacturing industries. Users need to test Machine tools at the time of purchase and also periodically during its use and operation. Evaluation needs to be done in accordance with relevant parts of National / International standards & procedures which can be broadly categorized into three areas, mainly Geometrical alignment test, Functional & Machine accuracy capabilities.
Conventional testing methods of machine tools are limited essentially to static measurements of geometrical alignments, and few functional tests under 'no load' conditions to qualify the machine performance and also for machine acceptance. However, the performance of a Machine tool is evaluated in terms of static and dynamic compliance to tolerances, surface finish of components and so on. These are essentially determined by static & dynamic accuracy of machine movements.
A proper knowledge of, Static & Dynamic aspects, Calibration aspects like positioning & repeatability, cutting trials on standard work piece will helps users in assessing the capability of the machine. The program also intends to highlight the technology under the skin of machine tool and suggestions/action plan to build efficient and accurate machine tools.
Keeping this in view, Indian Machine Tool Manufacturers’ Association (IMTMA) is organising a 3 hour programme on “Machine Tool Testing and Accuracy measurement of CNC Machine Tools” on 16th May 2020.
