METHOD FOR CONTROLLING A DEVICE SYSTEM HAVING A TOOL DEVICE AND A MOTOR-DRIVEN ADVANCING MECHANISM

摘要

A method for controlling a device system (10) having a saw blade (14) that is secured to a saw arm (15) and can be moved along an advancement direction (26) by means of a motor-driven advancing mechanism (13), wherein a delivery movement of the saw arm (15) with the saw blade (14) into the workpiece (18) takes place, during the delivery movement of the saw arm (15) into the workpiece (18) an arc length (Φ) of the saw blade (14) and in engagement with the workpiece (18) is calculated by a control unit (27) and the calculated arc length (Φ) is compared to a predefined critical arc length (Φkrit) of the saw blade (14).
