When the 20 mm - square shank tools are used machining should be perfomed at approximately 80% of the values shown above. For face grooving cutting depth and feed should be performed at approximately 70% of the values shown above. Cautionary Notes 1. When facing the operation should proceed from the OD toward the center in order to prevent tool breakage. 2. When performing OD machining the toolpoint must be set at a right angle to the axial direction of the work. 3. When replacing an insert the replacement should be made only after completely removing any chips or other foreign matter from the tool-clamping area on the holder by using compressed air etc. 4. Never tighten the insert-mounting screws when an insert has not been installed since doing so can deform the screws and prevent the future installation of an insert. 5. The inserts in Flex-Tools move upon the application of cutting force to form an end-cutting edge angle that suppresses chattering during OD-machining operations. For this reason when performing OD cutting the danger exists that the programmed dimensions for the work diameter will not be achieved if the machining conditions (cutting depth and feedrate) are set too high. If this is found to be the case it is necessary to perform a compensation in the program by an amount that is equal to the amount of A-A (the amount of OD compensation) that is shown in the drawing on the right (refer to the values for the amount of OD compensation that are given in the graph below the drawing.)
