moldmakingtechnology.com 75 imts.com September 12–17, 2016 / Chicago, IL CAM Strategies Improve Machining Times Open Mind Technologies USA will present its HyperMill Maxx Machining, a set of high-performance strategies within HyperMill CAM for improved roughing, drilling and finishing. The Maxx Machining Roughing module is based on Celeritive's Volumill toolkit and is designed to provide increased cutter life while reducing roughing times. It can be applied to 2D pocketing routines, 3D stock roughing and five- axis shape offset roughing. Maxx Machining Drilling is used to open holes for roughing using a five-axis helical drilling processes. It can use standard end mills and avoids recutting chips, thus protecting the cutter. The Maxx Machining Finishing module includes a set of finishing operations focused on the application of conical barrel cutters. This can be applied to large planar surfaces found in mold tooling, as well as in aerospace structural components and other large ruled or sculpted surfaces. The large radius on the conical barrel cutter enables large stepover distances and can achieve high surface finish. Open Mind Technologies / openmind-tech.com / Booth E-3351 Grade for Steel Turning Increases Tool Life Sumitomo's AC8025P grade for steel turning is designed to increase produc- tivity in a variety of steel turning applications, such as continuous, light-inter- rupted and interrupted cutting. The grade features the company's Absotech platinum CVD coating combined with a tough carbide substrate to resist adhe- sion and cutting-edge chipping. The smooth surface treatment is designed to improve adhesion resis- tance along the ridgeline of the cutting edge. When machining low-carbon steel, rolled steel and other materials prone to adhesion, the grade is said to increase tool life by reducing problems such as peeling or chipping of the coating layer at the cutting edge and deterioration of surface finish.
