Method and system for determining the wear of a drill bit in real time |
摘要 |
A method and a system are disclosed for determining the wear of a drill bit in real time. At a predetermined point prior to engagement of the drill bit with the workpiece, a first rotational speed of the drill bit is ascertained. Upon exit of the drill bit from the workpiece a second rotational speed is determined. Measurement of these two rotational speeds enables a determination to be made of the loss of energy resulting from the drilling operation. This loss in energy is used to produce a measure of drill bit wear.
