Five-axis machining center coordinate system determination method based on 7-point detection repetition

Abstract

The invention discloses a five-axis machining center coordinate system determination method based on 7-point detection repetition and belongs to the field of online measurement of numerical control machining. The five-axis machining center coordinate system determination method based on the 7-point detection repetition changes the traditional manual coordinate system aligning and machining which waste time and labor, and the aligning quality is partial to the processing experience of an operator. The five-axis machining center coordinate system determination method based on the 7-point detection repetition includes that mounting an infrared measuring head at the five-axis machining center, using the infrared measuring head to measure and sample points, calculating according to mechanical coordinate data of the measured points to obtain the rotating angle and zero point position of each of the fourth axis and fifth axis, and writing in a zero point offset table to realize zero point set. The five-axis machining center coordinate system determination method based on the 7-point detection repetition is simple in application conditions and suitable for the five-axis machining center with two rotary axes at a working table; the machining and detection are integrated through reasonably using an online measurement technology, the automatic alignment of the system is effectively realized, the part machining time is shortened, the workload of the operator is reduced, the potential quality hazard due to the alignment of the part machining is avoided, and the non-intervention processing for the part during the whole process is effectively guaranteed.

Description

technical field [0001] The invention belongs to the field of online measurement of numerical control machining, and in particular relates to a method for determining a coordinate system of a five-coordinate machining center based on a seven-point detection cycle. Background technique [0002] At present, the traditional method of determining the five-coordinate machining center requires manual alignment after the workpiece is clamped and clamped. Every time the operator processes a new part, it is necessary to manually align and add the dots of the work mark. It is time-consuming and labor-intensive, and it will take a lot of time and energy to find out the quality of the processing methods and experience of the operator, and the error rate is high, resulting in high labor intensity for the processing personnel, low processing efficiency of the parts, and the quality of the processing of the parts cannot be guaranteed.
