Аннотация: Abstract: The quality of CNC machines and their control systems is assessed in terms of the contour accuracy, consisting of two components: the accuracy in sending the signal confirming that the working component has reached the specified coordinate; and the accuracy in executing the stop command, given the inertia of the actuators. Recommendations are made regarding the selection of the device for monitoring the motion of the working components in a CNC machine with a gapless gear transmission and a torsional motor. If the required positional accuracy is low, it is acceptable to disregard the error in the gear ratio of the mechanical transmission between the sensor and the guide screw (or any other device converting rotation into linear motion). When using a device for monitoring the motion of the working components in a CNC machine, the adjustment of the sensor at the center of the scale interval should be as precise as possible. © 2021, Allerton Press, Inc.
