Video: Maximizing Cutter Life
A shop owner describes his simple approach to evaluating cutting tool performance and finding the best parameters.
Doug Noxell, owner of Surkut Machine Technology in London, Ontario, describes how he evaluates cutting tool performance to ensure that he is running at the best parameters. “In the first 10 or 15 minutes, you can get a lot of information,” he says. Once wear has begun, the level of wear or chipping indicate specifically how to adjust speed and feed rate. In this video from MMSOnline contributor Todd Schuett, Mr. Noxell explains his tool-observation technique.
The more common twist drill point geometries often are not the best for the job at hand. By choosing the best point for the material being drilled, it is possible to achieve better tool life, hole geometry, precision, and productivity.
Creating threaded holes in titanium alloys calls for proper techniques based on an understanding of both the properties of these materials and the peculiarities of the tapping process.
Applying ceramic inserts is not a simple substitution of one cutting tool material for another. There are significant process considerations that shops should examine carefully in order to realize performance and tool life expectations from ceramic inserts. Here's a look at some of the ways they are used.
