Abstract
A protection apparatus for a machine tool, at least for protecting a workpiece surface against overheating, includes at least one sensor unit and at least one evaluation unit. The sensor unit has at least one sensor element. The sensor element detects at least one characteristic variable of a fluid flow provided for transporting material removed from a workpiece. The evaluation enables identification of at least one temperature of a workpiece surface of the workpiece to be machined via the machine tool based at least in part upon the at least one characteristic variable detected via the sensor unit.
Claims13
A protection apparatus of a machine tool for protecting at least a workpiece surface against overheating, comprising:
- at least one sensor unit including at least one sensor element that detects at least one characteristic variable of a fluid flow provided for transporting material removed from a workpiece;
- and
- at least one evaluation unit that enables identifying at least one temperature of a workpiece surface of the workpiece to be machined by the machine tool based at least in part upon the at least one characteristic variable detected via the at least one sensor unit,
- wherein the at least one sensor unit further includes at least one further sensor element that detects at least one characteristic volumetric flow rate variable of the fluid flow.
A machine tool system, comprising:
- a machine tool that includes
- at least one protection apparatus that has:
- at least one sensor unit with at least one sensor element that detects at least one characteristic variable of a fluid flow provided for transporting material removed from a workpiece;
- and
- at least one evaluation unit that enables identifying at least one temperature of a workpiece surface of the workpiece to be machined by the machine tool based at least in part upon the at least one characteristic variable detected via the at least one sensor unit;
- and
- at least one suction removal apparatus configured to provide the fluid flow,
- wherein the at least one sensor element is positioned in the fluid flow.
