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.
Claims44
A method for determining a wear state of a milling tool including a chisel, the method comprising;
- determining using a distance measuring sensor a position value of at least one point on the chisel by either measuring or calculating the position value;
- and
- comparing the position value in a switching unit to at least one reference value 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 measuring sensor, the method comprising:
- (a) determining a position value of at least one point on the milling tool using the measuring sensor of the measurement system;
- and
- (b) determining the wear state of the milling tool by comparing the position value to a reference value.
