Abstract

Taylor's equation has proven utility for determination of the lifetime of cutting tool in machining of metal. Whereas, Taylor's equation is not widespread for prediction of wear of wood machining tools due to lack of appropriate coefficients of the equation. Therefore, aim of the study is determination of coefficients of Taylor’s equation. Computer numerical control machine was used for conventional milling of aspen (Populus tremula L.) wood with cutter knives of high-alloy tool steel X150CrMo12 on the cutter head. Changes of the surface roughness characterized the wear phases of cutting tool at two different values of cutting velocity were obtained depending on length of the cutting trajectory. It was concluded that length of cutting trajectory is greater when cutting velocity is increasing from 20 to 40 m s-1 and it was obtained equation to predict length of cutting trajectory till critical wear phase of cutting tool depending on the cutting velocity.
