Abstract
A machine tool device in one embodiment is configured to provide open-loop and/or closed-loop control of at least one machine tool function of a portable machine tool. The machine tool device includes at least one detection unit configured to detect at least one characteristic variable of the machine tool and/or of a processing tool arranged on the machine tool. The machine tool device further includes at least one brake unit, wherein at least one brake function of the brake unit is adapted at least partially automatically, and in particular dynamically, depending on the at least one detected characteristic variable.
Claims14
A power tool device for at least one of an open- loop and closed-loop control of at least one power tool function of a portable power tool, comprising:
- at least one acquisition unit configured to acquire at least one characteristic variable of at least one of the portable power tool and a work tool arranged on the power tool, which comprises at least one braking unit,
- wherein at least one braking function of the braking unit is configured to be adapted at least partially dynamically, in dependence on the at least one characteristic variable,
- wherein the at least one characteristic variable is a wear characteristic variable,
- wherein the acquisition unit has a wear acquisition element configured to acquire the wear characteristic variable of the at least one of the power tool and the work tool, and the braking function is configured to be adapted, at least partially automatically, in dependence on the wear characteristic variable, and
- wherein the wear characteristic variable is correlated with a change in weight of the power tool.
The power tool device as claimed in 1, wherein:
- the at least one characteristic variable includes a drive characteristic variable;
- and
- the acquisition unit has a drive acquisition element configured to acquire the drive characteristic variable of a drive unit of the at least one of the portable power tool and the work tool, and the braking function is configured to be adapted, at least partially automatically, in dependence on the drive characteristic variable.
