Three-dimensional color graphic dynamic tracking synchronous display for realizing virtual machine tool measurement system measurement trajectory
For the numerical control module controlled by the economical single-CPU general-purpose microcomputer, it is difficult to realize synchronous display due to the limitation of the performance of the hardware system. The numerical control module we designed is based on multi-CPU structure. The main control (PC) CPU generates the measurement motion control command and sends it to the PMAC. The PMAC multi-axis controller receives the control command for discrete interpolation and other processing, and then outputs it through the output channel. The control signal specifically controls each servo motor to complete the motion control work.
During the processing time of the PMAC motion controller, the main control CPU simultaneously performs processing such as real-time generation and display of measurement data and analog graphics, wherein the required data can be communicated between the two processors via bus or directly from two. The processor is shared in the dual-port RAM, thereby realizing the dynamic tracking synchronous display of the three-dimensional color graphics of the virtual axis machine tool measurement system measurement trajectory.
Synchronous display data acquisition PMAC motion controller is one of the most powerful motion controllers in the world. In addition to the required motion program, it can efficiently complete the required processing work and perform corresponding control output. Other processing tasks are performed within the processor cycle, including communication with the host, dual port RAM, and storage and update of motion process data.
