Machining Parameters Influence on Cutting Force Used for Tool Path Optimization in End Milling

Abstract

Tool path in contour milling needs to satisfy geometric criterion by adjusting the shape to the feature to be machined as well as other criteria in terms of cutting forces, tool wear intensity and desired surface quality. Researchers developed various cutting force models which take into account cutting force dependence on machining parameters such as cutting depth, feed rate and cutting speed. Some of this parameters directly depend of tool path geometry, so selection of tool path indirectly influences on cutting force, tool wear and surface finish. This paper presents overview of existing cutting force models for end milling and analysis of machining parameters which are used. Cutting force model capability to describe influence of tool path dependent parameters is used for selection and adaptation of model for further research in tool path optimization.
