Whether the woodworking engraving tool wears or the amount of wear, the most direct way to judge is to listen to the sound. If the cutting sound is very heavy or screaming, it means that the machining state of the tool is not normal. At this time, a brief analysis can be performed, if the tool itself is excluded. Quality problems (such as a new knife processing sound is not normal), tool clamping problem (no improvement in processing sound after re-clamping the tool), knife parameter problem (correct cutting amount, lower feed rate, processing sound still no significant improvement At this time, it should be judged that the tool is worn out, and it is necessary to suspend the machining and replace the engraving tool.
In addition, it is also possible to judge the wear condition of the tool by the running state of the engraving machine in the machining. If the setting of the machining parameters and the cutting amount are reasonable, the machine tool vibrates greatly during the machining, and a squeaking sound is emitted. At this time, it can be determined that the tool has continued. In the worn state, then even if the engraving machine tool is replaced.
