Embodiment Construction

[0041] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0042] see figure 1 , the present invention proposes a five-axis CNC machine tool space error detection method based on RTCP, which is realized by the following steps:

[0043] S1. According to the movement range of each axis of the machine tool, set the detection points of the two rotation axes, and combine all the detection points of the two rotation axes one by one to obtain the detection position of the rotation axis of the detection point.

[0044] In this embodiment, according to the range of motion of each axis of the machine tool, the detection numbers of the rotation axes A and C are respectively set, and the detection points of the rotation axes A and C are respectively obtained by dividing the range of motion of each rotation axis according to the detection numbers. , combine all the detection points of the rotation axis A and C one by one to...

Abstract

The invention provides a five-axis numerical control machine tool space error detecting method based on a rotation tool center point (RTCP), and belongs to the technical field of numerical control machine tool detection. To solve the problems that a traditional space error detecting method generally can be used for only detecting a single-axis error in a single time, multiple times of detecting are needed, consequentially, the consumed time is long, the efficiency is low, and a five-axis linkage error fail to be reflected, according to the five-axis numerical control machine tool space error detecting method, based on the RTCP function of a five-axis numerical control machine tool, machine tool five motion axis detecting positions are established with the arranged rotation axis detecting positions as the reference by means of a space error transfer model, single errors of all axes are described as a polynomial function related to the positions of the axes, the polynomial coefficients of all errors are subjected to inverse solving through tool point detecting results, and finally, the whole machine tool work space errors are detected. By means of the five-axis numerical control machine tool space error detecting method based on the RTCP, the five-axis numerical control machine tool space error detecting efficiency is improved, the detecting process is simplified, the detecting cost is lowered, and meanwhile, the machine tool five-axis linkage precision can be reflected in the detecting process.

Description

technical field [0001] The invention belongs to the technical field of numerical control machine tool detection, in particular to an RTCP-based five-axis numerical control machine tool space error detection method. Background technique [0002] CNC machine tools are mechatronic equipment with digital manufacturing technology as the core, consisting of control systems, servo systems, mechanical execution systems and other auxiliary systems. Traditional manufacturing is dominated by three-axis machine tools, but with the demand for complex-shaped parts such as some key aircraft parts, engine impeller blades, turbine blades, etc., five-axis CNC machine tools have gradually been widely used. Compared with the three-axis machine tool, the five-axis machine tool has two rotation axes added to the structure, so that the tool can achieve a specific machining posture in the work space through the movement of the rotation axis, so that the five-axis CNC machine tool has better flexibi...
