Abstract

This invention releases to a kind of compilation type numerical control system and how to use it. The system is a kinetic control system which made up with the machine tool and robot etc. mechanical equipment. It settles the problem like openness ability feebleness, commonality feebleness and real-time serviceability feebleness by using windows system. It can proof the numerical control code treatment at first and according to the speed of the numerical control code to blocking and baling the data. And then it sends the block data into the high-capacity data hold and runs it. In this process, it can switching run the data in the two high-capacity data hold, so this can make the real-time sending order and controlling message happened.

Description

technical field [0001] The invention belongs to a numerical control system for motion control of mechanical equipment such as machine tools and robots, and relates to technical fields such as mechanical engineering, electric automation, computer and communication. Background technique [0002] Computer Numerical Control (CNC) system is the core component of machine tools, robots and other mechanical equipment. From the perspective of the overall system structure, CNC systems can be divided into two categories: closed architecture and open architecture. The closed CNC system is composed of special microprocessors, special hardware and special software. The systems provided by different manufacturers lack interchangeability, and the openness and scalability to users are poor. If users need to add new functions, It must be completed by the manufacturer, the development cycle is long and the efficiency is low, so the numerical control system gradually develops from a closed str...
