Embodiment Construction

[0048] In order to further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0049] As attached Figure 1-3 As shown, the present invention discloses a length compensation method for sawing profiles of a cutting machine tool, which includes the following steps:

[0050] S1, establish a cutting force model during sawing in the machining process.

[0051] S2, establish an aluminum profile deformation model.

[0052] S3, set the interpolation cycle, and establish a sawing process expert database based on the known information of the aluminum profile and the nonlinear relationship between the cutting error and the cutting area. The corresponding relationship between cutting error and cutting area is nonlinear, that is, the larger the cutting area, the smaller the cutting error.

Abstract

The present invention discloses a length compensation method of saw cutting of section bars through a cutting machine. The method comprises the following steps of: S1, establishing a cutting force model when sew cutting is performed in a processing process; S2, establishing a section aluminum deformation model; S3, setting an interpolation period, and establishing a saw cutting processing technology expert database according to known section aluminum information, cutting errors and cutting areas; and S4, performing cutting track planning according to the saw cutting processing technology expert database to perform error compensation of the position of a cutting disc and complete processing. The method effectively improves the processing accuracy and improves the processing quality.

Description

Technical field [0001] The invention belongs to the technical field of sawing processing, and more specifically is a length compensation method for sawing profiles of cutting machine tools. Background technique [0002] The source of machining error in sawing can be divided into constant system error and variable system error according to the cause of the machining error. Constant system errors include machine tool-tool-fixture manufacturing errors, wear errors of various parts of the machine tool, and machining principle errors. Variable value system errors include errors caused by tool wear, heat, and force deformation. The error caused by the sawing force and the error caused by the thermal deformation are the main causes of the length error of the sawing profile. [0003] In order to ensure the accuracy of the machined surface, there are two common methods for reducing and eliminating errors: [0004] Error avoidance and error compensation. Error avoidance is the use of error...
