The technical practice requirements comes to have increased demands on higher productivity, speed and quality of the machining process of various materials. Hard to machine materials, whose machining led to the development of turning with rotating cutting edge are not an exception. The machining process of auto-rotating tool is more complicated than the conventional process of turning, especially for the process of reshaping cutting layers into chips. There is a significant load in the system, that may affect the life of the cutting edge of the tool as well as the whole system and also in the final extent of the qualitative parameters of the workpiece (product / product). The article specifies the knowledge and findings of measurement in machining material 100Cr6 with an auto-rotating tool. The measurements were conducted to evaluate the integrity of the surface (roughness) of the workpiece to the impacts of cutting conditions, in particular the feed and the cutting edge inclination. It also analyzes the presence (size, character, action) of residual stresses concentrated in the surface layers of the workpiece by changing the cutting conditions.

The article deals with the mathematical model of the primary contact of a milling tool in face milling. When designing the mathematical model, there were taken into consideration positive and negative geometry of the cutting wedge with different angle of taking instrument. Mathematical model is the input for experimental verification of the primary contact of milling tool and is aimed at improving the process of milling.

W artykule przedstawiono model matematyczny pierwszego styku ostrza skrawającego z materiałem obrabianym w procesie frezowania czołowego. W opracowaniu modelu uwzględniono narzędzia skrawające o ujemnej i dodatniej geometrii ostrza w różnym położeniu. Uzyskane zależności stanowiły podstawę do wykonania doświadczalnej weryfikacji procesu frezowania czołowego z uwzględnieniem wpływu geomertrii pierwszego styku ostrza z materiałem obrabianym na parametry wynikowe procesu w celu poprawy jego efektywności.
