44 MMS March 2017 SHOP TALK BY J E D D CO LE Dapra Corp. has had a technical center in Rock- ford, Illinois for several years. During that time, the cutting tool manufacturer, like many other OEMs, has conducted training sessions there for its e nd use rs and distr ibutors. Re ce ntly, however, the company decided to make a change to its training model in response to customer comments about the dif ficult y of finding and training skilled labor. Product Manager Mike Bitner says that until recently, the two-day seminars had been similar to other vendor-sponsored classes, with ample marketing material included in the training. In fact, it's been a common complaint from custom- ers that training sessions put more time into product features and benefits than on practical machining training. "Dapra decided to change that format and dedicate 100 percent of the time to technical milling training," Mr. Bitner says, adding that this training can be applied to any TOOL MANUFACTURER COMMITS TO MARKETING-FREE MODEL FOR PRODUCT TRAINING SEMINARS supplier's solid or indexable milling tools. In a recent article, Mr. Bitner outlined the cov- ered topics. They include choosing speeds and feeds from supplier literature; using speed and feed formulas; climb vs. conventional milling; long-reach milling considerations; selection of toolholder style; air vs. coolant tooling; coarse- pitch vs. fine-pitch tooling; inser t grades and geometries; soft vs. hard milling techniques; chip thinning (axial and radial); chip formation and tool pressure based on cutting geometry; tool path selections; and troubleshooting, including wear and failure characteristics. The program is intended for anyone involved in the milling process, from programming through setup, Mr. Bitner says. The idea is to have on-site field personnel spend the time to educate custom- ers fully on the product rather than simply con- ducting a test that earns a sale. This saves time for customers by reducing the need for trial and Attendees calculate speed and feed with the assistance of Dapra's applications specialists during a training seminar at the company's Mid- west Technical Center in Rockford, Illinois.
