Abstract

The invention relates to a calibration method for a measuring probe for online measurement in a processing machine tool, which is used for carrying out calibration on an online measuring probe of a mechanical processing machine tool. The calibration method is characterized by comprising the steps of one, installing a standard measuring bar on a machine tool calibrated element, on which the standard measuring bar can be fixed, to act as a calibration reference; two, touching any positions of the standard measuring bar for multiple times by using the measuring probe, and recording coordinate data of the measuring probe in touch; three, processing the measurement data recorded in the step two, and fitting to acquire a semicircle outline; four, calculating position coordinates of the center by the semicircle outline acquired by fitting, and carrying out geometric processing on the center coordinates, the center and the radius of the standard measuring bar, and the radius of the measuring probe so as to acquire coordinates of the center of the measuring probe. The calibration method provided by the invention has the advantages of simple design structure and installation process, ability of saving the space and low cost.

Description

technical field [0001] The invention belongs to the field of mechanical processing, in particular to a calibration method for a measuring probe of a processing machine tool. Background technique [0002] Machining is the basic operation of advanced manufacturing technology and the most basic and active link in the advanced manufacturing system. Its basic goal is to ensure the quality of products under the conditions of low cost and high productivity. Machining online measurement technology can measure the workpiece on site, give real-time feedback on the quality of assembly and processing, and to a certain extent, perform real-time compensation for tool wear and temperature rise online to improve processing accuracy and quality. Especially under the conditions of multi-variety and small-batch production, it is of great significance to study advanced on-line measurement technology, because on-line measurement is an important part of processing and measurement integration tech...
