If the operation start position is set in a block which is in the middle of the program and the program is
started, the program before the set block is not executed. Please confirm that G and F modal and
coordinate values are appropriate. If there are coordinate system shift commands or M, S, T and B
commands before the block set as the start position, carry out the required commands using the MDI, etc.
If the program is run from the set block without carrying out these operations, there is a danger of
interference with the machine or of machine operation at an unexpected speed, which may result in
breakage of tools or machine tool or may cause damage to the operators.
Under the constant surface speed control (during G96 modal), if the axis targeted for the constant surface
speed control (normally X axis for a lathe) moves toward the spindle center, the spindle rotation speed will
increase and may exceed the allowable speed of the workpiece or chuck, etc. In this case, the workpiece,
etc. may jump out during machining, which may result in breakage of tools or machine tool or may cause
damage to the operators.
