Can 1, tool wear, the wear quantity, the size of the most direct discriminant method is to listen to the voice, if the voice screamed very heavy or sharp cutting, clarify the cutting tool machining status is not normal, can stop briefly at this time, if remove the tool itself quality problem, woodworking carving machine tool clamping problem, problem of parameters with the knife, at that time, it should be able to distinguish the tool wear, demand to suspend processing, change the cutting tool.
2, after processing of the machine tool motion to tool wear condition, if the processing parameters, cutting parameter Settings are reasonable, such as processing of the machine tool vibration is very big, issued a "buzz", at this time can certainly arrived at the dreadful state of cutting tool and demand change tool.
