They are only guidelines from which further optimization should take place. Operating param- eters are influenced by many machining variables. These variables may cause for reductions in feeds and speed or dramatic increases. Additionally, DOC and WOC may need to be revised to optimize the tools performance. The success of any cutter application is a function of many variables. Our initial preference of grade is based on applying a more tough grade. 379
