Abstract
A machine tool having at least one motor-driven, movable machine part to which a braking apparatus, a distance measuring device for detecting a distance covered, as well as control device with display unit are allocated. A monitoring device for the brake effect of the braking apparatus is provided. The monitoring device has a memory unit containing stored values (RW, VW and AW) and a comparator. A deterioration of the brake effect is detected by comparing the braking distances detected by the distance-measuring device with the values stored in the memory unit, the display being activated if required.
Claims3
A machine tool comprising:
- at least one motor-driven, movable machine part having brake means, distance measuring means for detecting a distance moved, and control means including display means;
- and
- monitoring means for the brake effect of the brake means, said brake means comprising:
- memory means containing stored values;
- and
- a comparator;
- the monitoring means providing detection of a deterioration of the brake effect by comparing the braking distances detected by the distance measuring means with the values stored in the memory means, the display means being selectively activated.
A method of determining the functionality of a braking apparatus of movable parts in a machine tool, said method comprising:
- moving at least one motor-driven, movable machine part, said part having brake means, distance measuring means, and control means including display means;
- applying the brake means, the brake means comprising:
- memory means containing stored values;
- and
- a comparator;
- using the distance measuring means to measure the distance the machine part moved during the brake application;
- comparing the braking distances detected by the distance measuring means with the values stored in the memory means;
- and
- activating the display means;
- wherein if the braking distance measured is greater than the values stored in the memory means, a warning is indicated by the display means, thereby providing an indication of the functionality of the braking apparatus of movable parts in the machine tool.
