The control of the motor of CNC carving and milling machine

CNC engraving and milling machine motor rotation is controlled by the input pulse, each control pulse corresponds to a certain Angle of rotation so adjust the time interval between the control pulse equivalent control CNC engraving and milling machine of the rotational speed of the motor.
about how to control the time interval between pulses, CNC engraving machine co. , LTD adopts a kind of precision under Win9X for microsecond timing technology. Is briefly described as follows:
how much Windows multitask mechanism can affect the accuracy of timing, we can adopt the following two measures to improve. One is to improve the CNC engraving and milling machine carving monitor the thread priority level, the second is when CNC engraving and milling machine carving try not to run other programs of CPU time. Using this scheme establishment of sculpture monitoring program can completely meet the requirements of real-time control.
CNC engraving and milling machine > motor drive has its characteristics, including in particular: CNC engraving and milling machine motor should avoid the rotation rate of mutation, and from stop to around to have a lower start frequency, then can gradually transition to high speed when the motor brake accordingly, should also be smooth transition.
using the control pulse, means that the discrete digital control mode. Hardware with adjustment of pulse interval to speed. Accordingly, when the software implementation, can set a time interval list, each corresponding to a rotational speed in the table. Time interval according to certain rules change, making the stepper motor speed changes according to the law of uniform acceleration.
