This report deals with the way to decide tool posture, the way to analytically calculate tool path and the way to check the interference between tool system and work one. In the tool path calculation, basic equations are derived using the principle that the tangent slope at a cut point on a work and the one at a cutting point on a tool edge are identical. A tool posture decision procedure using the tangent slope at each cut point on a work is proposed for any shape of tool edge. A checking method for collision interference between a tool system (tool, tool holder, spindle head etc.) and a work system (work and its fixing equipment etc.) is also shown. The reliability and calculation efficiency of this algorithm is verified by test cutting of an impeller.
