Problems solved by technology

[0002] In the process of CNC machining, the servo interface of the current servo controller uses a high sampling rate (that is, the sampling period is short) for the data instructions sent by the CNC controller. The internal servo interface of the CNC controller is compared with the servo interface of the servo controller The use of low sampling rate (that is, the sampling period is longer), which leads to the servo controller not being smooth when controlling the movement of the servo motor, causing the servo motor to move discontinuously during the motion process, and sometimes it is necessary to use multiple servo motors to control The tool moves, which will cause all the vibration of the servo motor to be transmitted to the tool at the end, so that the motion curve of the drive is a stepped curve image instead of a smooth curve image, such as figure 1 As shown, this will reduce the machining accuracy of the tool due to vibration during machining

Abstract

The invention relates to a cutter path control method applied to a numerical control system, the numerical control system comprises a CNC main controller and a plurality of servo controllers, each servo controller is connected with the CNC main controller, and the CNC main controller comprises a human-computer interface main controller, a compiler, an interpolation compiler and an interpolation actuator; the human-computer interface controller is used for outputting processing information and displaying an image transmitted by the compiler; and the compiler is used for receiving the processing information transmitted by the human-computer interface controller, processing the processing information into corresponding images and transmitting the images back to the human-computer interface controller, so that the driving part can stably and continuously move through the control method instead of rapidly starting and rapidly pausing discontinuous movement. Therefore, the situation that the machining precision is affected by intermittent shaking caused by multiple times of quick start and quick pause of the driving part in the moving process of the tool can be avoided.

Description

technical field [0001] The invention belongs to the technical field of numerical control machining, in particular to a tool path control method applied to a numerical control system. Background technique [0002] In the process of CNC machining, the current servo interface of the servo controller uses a high sampling rate (that is, the sampling period is short) for the data commands sent by the CNC controller, and the internal servo interface of the CNC controller is relative to the servo interface of the servo controller. Using a low sampling rate (that is, the sampling period is long), the servo controller is not smooth when controlling the movement of the servo motor, resulting in the discontinuous movement of the servo motor during the movement, and sometimes it is necessary to use multiple servo motors to control The tool moves, which will cause the jitter of all servo motors to be transmitted to the tool at the end, so that the motion curve of the driving part is a ste...
