The multi-patches structure are widely used in various types of complex structure products such as the snubber of blade in the engine manufacturing industry. These parts are often machined with five-axis machine tool. When using the normal tool path planning method, it will be difficult to offset the surfaces and there will be redundant cutter retraction. In order to solve the above problems, this...
Instantaneous chip thickness during three typical end milling processes is analyzed in this paper. The tooth trajectory of a milling cutter is a combination of two motions, one is the rotation of the cutter spindle and the other is the feed motion of the cutter relative to work-piece. For simplification traditional chip thickness models always simplify the tooth trajectory as a circle to get approximate...
Focusing on the tool orientation control in multi-axis milling of freeform surface blade, quaternion interpolation method is employed to get smooth and collision-free tool orientation. Presented tool orientation planning method is based on the blade's shape features, it can avoid collision between the tool and the platform surface. Tool orientations on the boundary curves of the machining area are...
