Summary:The issue of tool wear in the machining of non-metallic materials is a very under-researched area. The theory is based on the findings known in metals and is extended by interaction of the tool with wood-based materials. These materials have completely different properties, most of them are characterized by poor thermal conductivity and a different behaviour in different directions of load (axial, radial and tangential). The course is based on a tool wear in the wear curves. Criterion wear defines the maximum wear -- a period corresponding to the working state of edge. Studying the process of wear is monitored mainly to determine dependencies between the durability of the cutting tool and the cutting speed. Addiction is characterized by Taylor's relationship. Measurement of tool wear in metal materials was carried out mainly on the back or top rake. However, for non-metallic materials, this wear is negligible and difficult to measure. This article is focusing on the issue of defining and measuring the radial edge wear.
