In part 3 we know that solid tungsten carbide end mills have relatively sharp edges and an edge preparation is necessary for the coatings to adhere firmly to the substrate and avoid edge breakage, thus increase the stability, functionality and life span of cutting tools .Here we talk about machining strategy.
Machining Strategy
The correct solid tungsten carbide end mill selection thus depends on many factors, the most important being the correct machining strategy. In reality, constraining factors cannot be changed in most cases, i.e. machine tool, CAM system and component size, material, tolerances and shape. However, within this existing framework, a correct strategy approach can still be set and there are many ways where one can influence the machining result and fine-tune the cutting conditions by changing feeds, speeds and depths of cut related to the overall machining objective. Related to the main direction and the technological strategy chosen, the selection of the tool can be accomplished.
In this respect two possible avenues are evident:
1. Performance driven selections with highly specialized individual solid tungsten carbide end mills for best performance in for example side milling, slot milling or 3D milling, each one of them covered with its own tool, or
2. Application driven selections with few cutters but with a wide range of applications and more broad based appeal. The choice of either path will direct the user to a more narrow part of the wide range of available solid tungsten carbide end mill available.
