5 Optimal tool positions in 5-axis NC machining of sculpture surface

摘要

The present invention relates to optimization of the tool orientation for the five-axis numerical control machining, the tilt angle (α) and the angle of rotation (β) to each 0˚ reset the tool position, at which time the optimal if it satisfies the predetermined restrictive condition the step of determining a tool position and; If it does not satisfy the constraint, searching for a tool starting position for searching the boundary of the area and enables; Wherein obtaining the boundary of the possible area by calculating the keoseop height (h) thus determining an optimum tool posture; by using a through interaction, which is characteristic of the five-axis numerical control processing and the boundary search algorithm, (h) keoseop height the optimum position of the tool is able to efficiently determine which minimizes.
