Embodiment Construction

[0065] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0066] Such as figure 2 As shown, the overall tool axis optimization method based on the minimum change in cutting speed in the preferred embodiment of the present invention includes the following steps:

[0067] S1. Plan the cutting point and form the cutting tool path.

[0068] Specifically, the cutting points are planned on the surface to be cut, and the surface normal direction and the tool path tangent direction of each cutting point are obtained to form the cutting tool path.

[0069] S2. Set an expected tool axis vector direction for each tangent point. As the preferred direction, it reflects the orientation desired by the user.

[0070] S3. Establish a local coordinate...

Abstract

The invention discloses an integral cutter shaft optimization method based on minimum cutting speed change. The method comprises the steps of planning a cutting contact and forming a cutting tool path; setting an expected cutter axis vector direction for each cutting contact; establishing a local coordinate system for each cutting contact; determining a cutter shaft feasible region; establishing acutting speed mathematical model; and establishing a mathematical model for problem optimization. The integral cutter shaft optimization method based on the minimum cutting speed change can be suitable for curved surface cutting with various densely-arranged cutter paths, the cutting linear speeds between adjacent cutting contacts are close, each cutter path and the cutting linear speed between the cutter paths do not change suddenly, cutter marks and other marks left on the surface of a material after cutting are reduced, the machined surface quality is optimized, and the problem that an existing optimization method cannot achieve overall optimization on the premise that the cutter axis vectors of all cutter paths face different directions is solved.

Description

technical field [0001] The invention relates to the technical field of milling, in particular to an overall cutter axis optimization method based on the minimum change in cutting speed. Background technique [0002] The impeller discs of aircraft engines are made of difficult-to-machine materials such as high-temperature alloys and titanium alloys. When processing such materials, it is often necessary to maintain the tool posture as pulling or pushing throughout the process, which can reduce the torque on the tool and effectively prevent the tool from breaking. . And in the case of keeping the tool posture as push or pull throughout the process, it is necessary to use a bidirectional cutting tool path, because this can effectively shorten the transition tool path and improve processing efficiency, but currently there is no overall optimization of the tool axis suitable for this cutting method method. In the future, this cutting method will be referred to as bidirectional c...
