Relative coordinates programming:The end of the trajectory coordinates are relative to the starting point for measuring way of programming (incremental coordinates programming)
Parallel processing:Refers to the CNC software system at the same time or at the same time interval to complete the processing method of two or more than two tasks.The purpose of using parallel processing technology is to improve the utilization efficiency of CNC system resources and processing speed of the system.The realization of the parallel processing method is closely related to the hardware structure of CNC system
Before and back table structure:This kind of structure will be divided CNC system software into two parts: the front desk program and background.The former mainly complete interpolation calculation, position control, fault diagnosis and other real-time task, it is a real time interrupt service routine.Daemon (also known as the background programs) complete display, parts processing program of editing management, system input/output of interpolation, the place of the manager (decoding, knife repairing process, speed pretreatment) such as weak real-time tasks, it is a running program,in the process of operation, constantly timing was interrupted by a receptionist interrupt program, front and back table cooperate with each other to complete zero parts machining tasks.
