A method for controlling a device system () during the cutting of a workpiece () along a cutting line () up to a first end point (E) using a saw head () that can be moved on a guide rail () along an advancing direction (), whereby the saw head () is arranged on the guide rail () in a starting position (X), and a first partial length (L) extending from the starting position (X) to the first end point (E) of the cutting line () is entered.

Method for controlling a device system during the cutting of a workpiece along a cutting line

A device for cutting a workpiece along a cutting line between a first end point and a second end point including a saw head, comprising an advancing mechanism with a guide carriage and with an advancing motor. The saw head is arranged on the guide carriage movable along an advancing direction, including a sensor system with a sensor element for monitoring the saw head, the advancing mechanism or the work process, including a control unit with a control element to control the saw head, the advancing mechanism and the sensor system as well as an evaluation element to evaluate a measured quantity detected by the sensor system, including an operating device to operate the saw head and the advancing mechanism, and including a display. On the basis of the measured quantity, the control unit calculates the momentary work result which is shown on the display.

A method for controlling a device system () having a saw blade () that is attached to a saw arm () and that can be moved along an advancing direction () by a motor-driven advancing mechanism (), whereby there is an infeed motion of the saw arm () with the saw blade () into the workpiece () and, during the infeed motion of the saw arm () into the workpiece (), a control unit () calculates an arc length (&#x3c6;) of the saw blade () that is engaged with the workpiece (), and the calculated arc length (&#x3c6;) is compared to a pre-set, critical arc length (&#x3c6;) of the saw blade ().

A control method according for an impact wrench includes ascertaining whether the impact wrench applies an impact when the drive shaft rotates in a lower speed range. The speed of the drive shaft then is increased to a higher speed range as a function of an ascertained impact during the rotation in the lower speed range.

A handheld power tool, including a tool socket on a drive shaft for purposes of holding a tool, the drive shaft executing a rotating and partially tangentially striking movement using a tangential striking mechanism drivable by a drive. The tangential striking mechanism has an anvil associated with the drive shaft and a hammer associated with the drive, movable with respect to each other so as to strike each other axially when under the effect of the force of at least one first spring, and to strike each other tangentially when the anvil and the hammer are rotated. The hammer has a main mass, and an extra mass that is under the effect of a second spring couplable to the main mass.
