Evaluation of Micromachining Processes Using Data in the Format and Geometric Characteristics of Micro-Chips

Studies on micro-chips formed in the process of micromachining, including grinding and microfinishing using abrasive films, were conducted. Geometric characteristics of the micro-chips were analyzed and the presence of very long chips compared to their width was observed. One also reported the presence of very high temperatures in the treatment zone despite the applied cooling, which resulted in the formation of spherical chips. The occurrence of two characteristic spherical chip structures was observed followed by evaluation of their chemical composition. Based on the tabular structure of band chips, characteristic micro-discontinuities in the microcutting process were determined.
