New optical imaging system for determining wear criteria for cutting inserts

Abstract

In mechanical engineering, cutting tool wear is a major factor in the functional and parametric failure of a cutting tool. The loss of tool performance causes failures in the production of suitable products, as well as machine downtime. In this connection, accurate measurement of wear of the cutting wedge at various stages of the technological process is extremely important. The article proposes a method for recognizing wear zones on the back surfaces of cutting inserts by image processing. Indicators have been formed for assigning a failure criterion for various quality factors. For the formation of a measurement system, a three-stage control method with the rationale for operational recommendations is proposed. The correlation of wear by image processing has been compared with the optical method currently applied in manual mode, which greatly reduces the efficiency of production quality control.
