Researching the profile of normal wear of die face

Melnyk V. O.

Journal of New Technologies in Environmental Science

2018

Vol. 2, nr 3

116--120

In the article the geometrical form of natural wear of working surface of die is investigated. The research had done with using of the measuring system on the base of three-coordinate machine-tool with numerical program control. As a result of measuring were obtained set of points on which was built the experimental cross-sectional profile of the working surface of worn dies. It was found that profile of natural wear of die is described by the polynomial of the third order with the high degree of authenticity.
