Problems solved by technology

[0003] The measurement accuracy of the three-coordinate measuring machine is more accurate than that of ordinary measuring tools, but there must be measurement errors
Due to the error of the grating ruler reading system and the mechanism processing and assembly error of the three-coordinate measuring machine tool (such as the imperfection of the guide rail system), the measurement accuracy is seriously affected. The traditional method is to compensate the error by adjusting the mechanism part
This method is time-consuming and the effect is not obvious

Embodiment Construction

[0013] Such as figure 1 Shown is a hardware architecture diagram of a preferred embodiment of the error compensation system for a three-coordinate measuring machine tool of the present invention. The three-coordinate measuring machine tool error compensation system 4 includes a three-coordinate measuring machine tool 1 , a calibration standard device 2 and at least one client computer 3 . The three-coordinate measuring machine tool 1 includes a guide rail system 10 , which is the main cause of mechanism processing and assembly errors of the three-coordinate measuring machine tool. Calibration standard equipment 2, such as a laser interferometer, is used to detect the position error, straightness error and angular pendulum error of the three-coordinate measuring machine tool 1. The client computer 3 provides an operation interface for three-coordinate measurement machine tool error compensation, which includes the operation and operation of a measurement software 30, which is ...

Abstract

The present invention provides three measurement of coordinates machine tool error compensation system. Said system includes one input / output module, one computation module, one data security module, and one data storage module; wherein said input / output module used for data acquisition and error compensation result output; computation module used for error compensation calculation feeding back former coordinate value calculation; data security module used for file ciphering and deciphering in measurement and computational process for ensuring file security; data storage module used for surveying computation process generated different kinds of object file temporary storage, including each parameter and compensation file storage. The present invention provides three measurement of coordinates machine tool error compensation system. The present invention also provides three measurement of coordinates machine tool error compensation method. The present invention can rapid compensate error and reduce processing cost, and raise accuracy in measurement.

Description

【Technical field】 [0001] The invention relates to an error compensation system and method, in particular to an error compensation system and method for a three-coordinate measuring machine tool. 【Background technique】 [0002] Coordinate Measurement Machine (Coordinate Measurement Machine) is currently the most widely used large-scale general-purpose testing instrument, mainly including gantry type, column type, and robot arm type. The three-coordinate measuring machine is used to measure the dimensional error and shape error of parts and components, and plays an important role in ensuring the quality of products. [0003] The measurement accuracy of the three-coordinate measuring machine is more accurate than that of ordinary measuring tools, but there must be measurement errors. With the development of production, the requirements for measurement accuracy are getting higher and higher. Therefore, in order to make the measurement results of the three-coordinate measuring ...
