METHOD FOR CONTROLLING DEVICE SYSTEM HAVING TOOL DEVICE AND MOTOR-DRIVEN ADVANCING MECHANISM Russian patent published in 2018 - IPC B23D59/00 

FIELD: control; regulation.

SUBSTANCE: invention relates to methods for controlling devices with a working member and a motorised feeding device and can be used in the machining of workpieces by cutting. Method involves moving the saw arm against the saw blade to penetrate the workpiece, during which the length of the arc of the saw blade being engaged with the workpiece is calculated by means of a control device, comparing it with a predetermined critical length, if there is a match, stopping the movement of the saw arm and moving the saw blade in a forward direction along the feed direction. Calculating the advancement of the saw blade in the forward direction, comparing it with a predetermined first advance, and when they match, the said motion is interrupted and additional movement is made to move the saw arm into the workpiece, during which the arc length of the saw blade engaged with the workpiece is calculated and compared to the critical value of the arc length.

EFFECT: invention is aimed at increasing the speed of the saw blade and prolonging service life.
