Abstract
This invention relates to a method for determining a wear state of a chisel, a chisel holder, and/or a chisel holder replacement system equipped with a chisel and chisel holder. For this method to give the user qualitative and quantitative information about the wear, according to one embodiment of this invention, a position of at least one point of the chisel and/or the chisel holder is determined by a contactless measurement method and a corresponding measurement result is compared in a switching unit to a reference value stored in a memory device.

1-29. (canceled)
A measurement system for determining a wear state of at least one milling tool of a milling roller of a road milling machine or a surface miner machine, the measurement system comprising:
- a sensor associated with the machine and arranged to provide at least a sensor output that varies in relation to a distance between the sensor and the milling tool;
- and
- a processor configured to determine the wear state of the milling tool at least in part by comparing the sensor output to a reference value.
A method for determining a wear state of a milling tool including a chisel, the method comprising;
- providing, using a sensor, a sensor output corresponding to a distance of the sensor from the chisel;
- and
- comparing the sensor output in a processor to at least one reference value for the sensor output stored in a memory device to determine the wear state of the milling tool.
A method for determining a wear state of a milling tool mounted on a milling roller of a milling machine, using a measurement system mounted on the milling machine, the measurement system including a proximity sensor, the method comprising:
- (a) sensing a proximity of the milling tool to the proximity sensor of the measurement system, and providing an output signal from the proximity sensor, the output signal having a current value;
- and
- (b) determining the wear state of the milling tool by comparing the current value to a reference value.
