Corner movement
When a multiple number of offset vectors are created at the joints between movement command
blocks, the tool will move in a straight line between those vectors.
This action is called corner movement.
When the vectors do not coincide, the tool moves in order to machine the corner although this
movement is part and parcel of the joint block. Consequently, operation in the single block mode
will execute the previous block + corner movement as a single block and the remaining joining
mo following block will be executed as a single block in the following operation.
