| How to Select Five-Axis Advantage |
|
As with any significant investment, the first step in the purchase and implementation of a five-axis machine should be a thorough evaluation of its potential impact on current needs. A manufacturer producing simple parts with lax surface finish specifications will have significantly different requirements than one working with complex geometries and high surface finish requirements. By taking inventory of the demands to be met,
a shop can determine if a five-axis machine is the correct choice for its operations. After selecting a machine that matches the unique demands of its operations, a shop should then purchase five-axis CAM software that supports the chosen machine. If possible, it is ideal to obtain software that was developed in coordination with the machine tool builder. At a minimum, the CAM software’s post processor should have been developed with the support of the machine tool builder. It is important to verify this, as in many cases, the post processor may not be available, or may not be robust. Finally, tooling needs to be chosen to use in the new machine. In recent years, dramatic improvements have been made in tooling technology. For those cutting hardened steels, carbide cutting tools in particular feature innovations that provide particularly strong value. Improvements in sub-micron grain substrates, coupled with TiAlN coatings that achieve superior adhesion to the substrate, have dramatically improved the life of tools operated at high speed in hardened materials. In nearly all applications, the boosts to productivity and performance provided by high-performance tooling more than offsets its increased cost. This is a vital fact to keep in mind for those wishing to get the most out of their machine tool investment.
