Feed method preventing crash onto spindle of horizontal five-axis machine at swinging angle A/B

Abstract

The invention discloses a feed method preventing crash onto a spindle of a horizontal five-axis machine at a swinging angle A / B. The feed method includes that a feed track aid (4) in a cylinder form is set to cover a part (2) and a tool (3) for mounting the part; after a cutter (1) processes at a certain station, tip of the cutter (1) returns to the outer cylindrical surface of the feed track aid (4), then lifts to the top face of the outer cylinder and rotates with B angles, with the excircle of the aid as a virtual tip track and the center point of the top face of the outer cylinder as the center, along the excircle of the outer cylinder; after rotates with a required angle, the tip of the cutter (1), along the outer cylindrical surface, descends to the height of the next process station and moves forward for the process, in this way, the cutter (1) or the spindle never crashes onto the part (2) or the tool (3), and huge economic loss, caused by changing of the spindle and the part crashed, is avoided.

Description

technical field [0001] The invention relates to a tool-moving method for preventing the collision of the spindles of A and B swing angle horizontal five-coordinate machine tools. Background technique [0002] In the CNC machining industry, horizontal five-coordinate machine tools are widely used in factories due to their good chip removal, large swing angle range, and good rigidity. The process of machining parts with multi-axis linkage horizontal five-coordinate CNC milling machines with A and B structures In this case, when the tool of the B-axis finishes processing at a certain part of the part and changes to the next processing part, due to the limitation of the post-processing algorithm, when the B-angle rotation always rotates around the tool tip, the parts or tooling and the main shaft or the main shaft The interference and collision of the cutting tool on the machine tool will cause equipment accidents or parts scrapping accidents. In this way, replacing the machin...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the existing problem that when the tool of the B-axis finishes machining at a certain part and changes to the next machining part, because the B-angle rotation always rotates around the tool tip, it is easy to cause the tool or spindle to collide with the part or tooling. The invention proposes a tool-moving method to prevent the spindle collision of A and B swing angle horizontal five-coordinate machine tools
