9 WORKING CONDITION WHEN MILLING For optimal application of any milling tool, we recommend checking It is, of course, also necessary to take into account the geometry of chip thickness, or rather, using the recommended hm range to choose the indexable insert itself. To calculate fz, you can use the formulae (calculate) the proper feed rate. provided above or use the following formula. The values of coefficient c can be derived from the following chart: 4 fz = hmsin . kr.c Machining with the SIDE of the milling cutter3,51 3 2,5 c 2 1,5 1 2 Machining with the CENTRE of the milling cutter 0,5 0% 10 % 20 % 30 % 40 % 50 % 60 % 70 % 80 % 90 % 100 % ae /DC Each tool type listed in this catalogue has its own optimum range of average chip thickness. Using values lower than listed in this range may prevent the tool from cutting or, rather, may subject the insert to excessive wear and, in extreme cases, may even destroy it in the process. Similarly, exceeding the recommended values may destroy the insert by overloading the tool. The ranges of recommended average chip thickness are listed directly by each tool family. The full range of chip thickness can only be used for groups P and K. The lower limit of chip thickness must be adjusted (taken as higher than listed) for groups M and S and for tougher materials from group N. The upper limit must be lowered for groups H, S and slightly also for tougher materials from group M. On the contrary, it is possible to increase the upper limit of recommended average chip thickness by approx. 10 – 15 % when machining soft materials from group N.
