Embodiment Construction

[0047] In order to further understand the features, technical means, and specific objectives and functions of the utility model, the utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0048] as attached Figure 1-3 As shown, the present invention discloses a length compensation method for sawing profiles by a cutting machine, comprising the following steps:

[0049] S1, establishing a cutting force model during sawing during processing.

[0050] S2, establishing the aluminum profile deformation model.

[0051] S3, setting the interpolation period, and establishing a sawing process expert database according to the known aluminum profile information and the nonlinear relationship between the cutting error and the cutting area. The relationship between cutting error and cutting area is non-linear, that is, the larger the cutting area, the smaller the cutting error.

[0052] S4, plan the cutting traj...

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 relates to a length compensation method for sawing profiles by a cutting machine tool. Background technique [0002] The sources of processing errors in sawing processing can be divided into constant value system errors and variable system errors according to the causes of processing errors. The constant value system error includes the manufacturing error of the machine tool-tool-fixture, the wear error of each component of the machine tool and the error of the machining principle. The variable value system error includes the error caused by the deformation caused by tool wear, heat and force. The error caused by sawing force and the error caused by thermal deformation are the main reasons for the length error of sawing profiles. [0003] In order to ensure the accuracy of the machined surface, there are two common ways to reduce and eliminate errors: error avoid...
