1. Rear cutter face wear: (This is a common practical form)
Influence: the workpiece size gradually changes or the surface
light intensity decreases
Cause: The linear speed is too high, reaching the service life of
the tool
Measures: Adjust the processing parameters, such as reducing the
linear speed and using a blade with higher wear resistance
2. Blade breakage: (bad actual effect form)
Effect: sudden change of workpiece size or surface smoothness,
resulting in burrs on the spark surface
Cause: Improper parameter setting, improper tool face material
selection, poor workpiece rigidity, unstable blade clamping Measures: check whether the parameter setting is reasonable, and
select the corresponding tool according to the workpiece material
3. Serious fracture: (very bad actual effect form)
Effect: sudden and unexpected occurrence, resulting in scrapping of
tool handle materials or defective and scrapped workpieces
Cause: The processing parameters are set incorrectly, and the
vibrating tool workpiece or blade is not installed in place
Measures: set reasonable parameters, reduce the feed rate and chip,
select the corresponding processing blade, and strengthen the
rigidity of the workpiece and blade
4. Chips:
Effect: the size of the workpiece is inconsistent, the surface
finish is poor, and the workpiece surface is attached with fluff or
burrs. Cause: the cutting speed is too low, the feed is too low,
and the blade is not sharp enough
Measures: improve the cutting speed, and use blades with higher
sharpness for feed rate
