Abstract

The invention discloses a network cluster-control-based numerical control machine tool error real-time compensation system and a network cluster-control-based numerical control machine tool error real-time compensation method. The compensation system comprises a hardware part and a software part built in hardware, wherein the hardware part comprises a master control center personal computer (PC), a router, a built-in Ethernet port or a personal computer memory card international association (PCMCIA) Ethernet card, a temperature sensor and a temperature data acquisition card; and the software part comprises a temperature acquisition module, an error modeling and calculating module, a cluster-control compensation module and a machine tool state network monitoring module. By the compensation system and the compensation method, error real-time compensation and working state information monitoring can be performed on a plurality of numerical control machine tools on a production line at the same time; the movement precision of the numerical control machine tools is improved in batches; and therefore, the compensation efficiency and the final machining precision are greatly improved.

Description

technical field [0001] The invention relates to a machine tool error compensation device and method, in particular to a network group control-based CNC machine tool error real-time compensation system and compensation method, belonging to the technical field of CNC machine tool processing. Background technique [0002] Modern machinery manufacturing technology is developing towards high efficiency, high quality, high precision, high integration and high intelligence. Precision and ultra-precision machining technology has become the most important component and development direction of modern machinery manufacturing. With the wide application of precision machining technology, the requirements for the precision of CNC machine tools are increasing day by day. [0003] Machine tool error refers to the initial position error and motion error caused by inaccurate manufacturing, installation, motion control and other factors such as tool, bed and thermal deformation in the machine...
