Automatic electronic control of machine tools

Abtract One of the types of modernization of CNC machines is the replacement of outdated electronic control units with more functional and compact ones, made on a modern element base. However, in the course of work on the modernization of CNC machines, characteristic problems of electromagnetic compatibility arise. The report examines the features of the electromagnetic compatibility of equipment, blocks and assemblies of CNC machines during modernization. Based on the analysis of the factors characterizing the electromagnetic environment, typical failures of the electronic part of the control system of a CNC machine tool during testing, the need for the development of measures to ensure EMC is shown. All measures to ensure electromagnetic compatibility are not intended to reduce degradation, but to ensure the full implementation of all equipment functionality. General solutions are proposed that are applicable to the modernization of most second-generation CNC machine tools.

Chatter Marks

Ultramicrotomists live in a state of guerilla warfare with chatter. This situation is likely to be permanent. We can infer this from the history of machine tools. If set the wrong way for the particular combination of cutting tool and material, most if not all machine tools will chatter.In more than 100 years since machine tools became common, no one has evolved a practical recipe that guarantees avoiding chatter. Rather than follow some single very conservative rule to avoid chatter in all cases, machinists detect it when it happens, and change conditions until it stops. This is possible because they have no trouble telling when their cutting tool is chattering. They can see chatter marks, and they can also hear a sometimes deafening noise.
