Changing the Cutting Speed
If the material was not cut correctly (for example, if the result of the cutting test was
that two shapes peeled off together), reduce the cutting speed.
When the cutting speed is fast and the material moves up and down during cutting, an
excessive load will be applied to the material. In this situation as well, reduce the
cutting speed.
