C1Continuous Toolpath Generation Toward 5-axis High Speed Machining

Toward 5-axis High Speed Machining

We present a scheme to construct C1 continuous toolpath for 5-axis pocketing of high speed machining. A continuous toolpath synthesis is proposed, that forms out circular segments of maximally inscribed sizes and linear segments connecting these circular segments. Extending earlier work that employed the Medial Axis Transform to compute these maximally inscribed circles for 2D planar pockets, t...

MATHSM: medial axis transform toward high speed machining of pockets

The pocketing operation is a fundamental procedure in NC machining. Typical pocketing schemes compute uniform successive offsets or parallel cuts of the outline of the pocket, resulting in a toolpath with C discontinuities. These discontinuities render the toolpath quite impractical in the context of high speed machining (HSM). This work addresses and fully resolves the need for a C continuous ...

Toolpath generation method for four-axis NC machining of helical rotor

Purpose: This paper presented a method for generating the toolpaths for the machining of a helical rotor on five-axis machine tool. Design/methodology/approach: The geometry of the helical rotor is designed based on the ruled surfaces. Through the homogeneous coordinate transformation, the cutter location of the flank milling for four-axis machining can be generated. The postprocessor are devel...

Optimization of 5-axis high-speed machining using a surface based approach

This paper deals with optimization of 5-axis trajectories in the context of high-speed machining. The objective is to generate tool paths suited to high speed follow-up during machining in order to respect cutting conditions while ensuring the geometrical conformity of the machined part. For this purpose, the optimization of the tool axis orientations is performed using a surface model for the ...
