Virtual numerical control machine on-line detection system and method

Abstract

The invention discloses a virtual numerical control machine on-line detection system. The virtual numerical control machine on-line detection system comprises a computer, a measuring head, a receiver and a numerical control machine, wherein the measuring head is arranged on a knife handle; the receiver is matched with the measuring head; and the numerical control machine comprises a numerical control system. The virtual numerical control machine on-line detection system is characterized in that: the computer is provided with a virtual numerical control machine on-line detector; the virtual numerical control machine on-line detector acquires figure information of a measured workpiece from the computer and provides a human-computer interaction interface; the virtual numerical control machine on-line detector automatically generates a measurement main macroprogram according to measurement items selected in the human-computer interaction interface and the set test parameters; the measurement main macroprogram is uploaded to the numerical control system through the computer; and at the same time, the virtual numerical control machine on-line detector receives detection data output by the numerical control system through the computer, performs error compensation and analysis and computation on the detection data according to an error compensation value which is set by a user in the human-computer interaction interface, prompts the ultra-poor measurement item, and displays, stores and replays the computation result.

Description

technical field [0001] The invention relates to a numerically controlled machine tool, in particular to a virtual type numerically controlled machine tool online detection system and method realized by using virtual technical conditions. Background technique [0002] Due to the existence of secondary clamping errors in traditional measurement methods, the measurement accuracy and efficiency cannot be guaranteed. The online measurement and detection of CNC machine tools is more and more widely used in enterprises. The general CNC machine tool online inspection system is only equipped with a probe system. The measurement macro program needs to be manually written on the machine operation panel, and can only directly obtain the detection results of simple geometric dimensions. The detection of shape and position errors also needs to be carried out by other means. The calculation is cumbersome to operate, which seriously reduces the efficiency of online detection, and does not g...
