Embodiment 1
[0067] In order to enable those skilled in the art to better understand the technical solution of the present invention, and to make the above-mentioned purpose, features and advantages of the present invention more obvious and comprehensible, the present invention and its implementations will be further described in detail below in conjunction with the accompanying drawings.
[0068] like figure 1 As shown, a numerical control system based on high-speed timing / interruption interpolation processing includes a host computer 1, a high-speed interpolation device 2, a communication interface module 3, an interpolation controller 4, a servo drive system 5, a CNC machine tool 6 and a detection device 7 , wherein: the high-speed interpolation device 2 includes a man-machine interface module 2-1, a processing module 2-2, a timing / interrupt interpolation module 2-3, and a position control module 2-4; the man-machine interface module 2-1, the processing module 2-2, the timing / interrupti...
Embodiment 2
[0145] Implementation example 2 is on the basis of implementation example 1, and provides a kind of implementation example. This method is simple and easy to operate, such as Figure 7 As shown, implementation example 2 of the present invention realizes the steps of high-speed timing / interrupt interpolation control:
[0146] Step SP4-1: A CNC system initialization based on high-speed timing / interrupt interpolation processing;
[0147] Step SP4-2: cyclically read G code instructions;
[0148] Step SP4-3: Determine whether the interpolation data of the G code is received?
[0149] Situation 1: If the interpolation data of G code is received, the next instruction is high-speed timing / interrupt interpolation;
[0150] Case 2: If the interpolation data of the G code is not received, execute step SP4-1, a kind of CNC system initialization based on high-speed timing / interruption interpolation processing.
[0151] Step SP4-4: High-speed timing / interrupt interpolation:
[0152] Fur...
