[!]Specify an alteration position to be 2 mm or more away from the stepped part. (Refer to the diagram in Caution (1))
[!] When adding multiple alterations, there must be 2 mm or more clearance between each machined part. (Refer to the diagram in Caution (2))
[!]When flat machining, wrench flats, square chamfering and keyway alterations are combined with each other, their orientations will be random. (Refer to the diagram in Caution (3))
[!] Do not specify multiple alterations in such a way that they overlap with each other in the rotating direction on the same shaft. (Refer to the diagram in Caution (4))
[ ! ] When two or more alterations are specified on a shaft, they may not be machined due to correlation.

(One example of this is shown in the diagram below.) .gif) For Alterations A and B added to the same shaft, as shown in the diagram above, their orientations are random and thus, there are some cases where they are not aligned in a linear arrangement. | Caution (4) Do not specify multiple alterations in such a way that they overlap with each other on the same shaft.
