The latest tool presetting machines equipped with a full suite of tool management features and functions can play a big role in improving shop productivity component quality tool life inventory control whilst minimising down-time reducing component cycle times and part scrappage. Mounting and Adjusting Milling Cutters Possibly the most crucial cutter body to correctly mount and adjust for the individual cutting inserts is that of a side-and-face cutter Fig. 138 . The reason why it is important to set the cutter assembly up correctly is that invariably the width of the slot in the machined workpiece is identical to that of the respective rotating face widths of the cutting edges. Moreover whole cutter assembly must run true as it rotates on its arbor39 - with no discernible wobble - as this effective wobbling will influence the machined slot geometry. At its most extreme some of these special-purpose slotting cutters can be 2 tonnes in weight and larger than m in diameter having segmented cartridges that are precisely and accurately fitted onto the periphery of the cutter body. As a general rule of thumb most of these types of slotting cutters are used to machine component features to a depth of four times their slot width40. If a deeper slot is required then the cutter has to be optimised in some way. Perhaps by using a smaller width cutter than that required for the component s slot width and if possible cutting each slot face separately and eventually taking it to the desired width depth - arbor interference permitting. Mounting cutting inserts in the case of the staggered-toothed side-and-face cutter body shown in Fig. 138 is relatively straight forward due to the lateral adjustment available by the splined cartridge seatings. Here it is important to ensure that the insert seat is thoroughly cleaned prior to commencing fitment. Moreover ensuring that the contact against the bot tom face of the seat occurs prior to tightening .
