Don’t give any finish allowance (in rough cutting and medium finish
cutting) larger than or equivalent to the surplus thickness, otherwise the
blank figure may be deformed to unfavorably affect the subsequent
machining.
(Example)
If the surplus thickness is as illustrated in the left figure, for
example, the following finish allowance cannot be given.
Finish allowance in X direction 5 mm
Finish allowance in Z direction 5 mm
Don’t give such a surplus thickness as may exceed a blank dimension in
a special blank. It is recommended to give a relatively large blank
dimension so that the surplus thickness does not exceed the blank figure,
even if it is added to the machining figure.
