CAD/CAM Software

OPEN MIND Technologies, Needham, MA, has introduced its latest CAD/CAM software suite, which offers users new and enhanced features for efficient 3D and 5-axis machining, such as the hyperMILL® AUTOMATION Center Advanced option and more. New features in hyperMILL® 2020.2 include the addition of plunge-milling cycles to the 3D and 5-axis strategies for machining cutting edges. Material is removed by plunging movements to reduce vibration and improve surface finish, especially helpful for machining edges with steep walls. When 5-axis machining, undercut areas can also be reached by specifying the lateral inclination on the tilted tool.

Nickel Strip for Batteries

AMETEK Specialty Metals, Wallingford, CT, offers a precision nickel strip that is engineered for critical battery connector applications in the medical and other markets. The company uses wrought powder metallurgy to custom-make the strip, achieving a 99.98 percent purity, which delivers 15–20 percent higher conductivity than traditional cast strip materials and therefore provides greater power transmission in batteries. Power is carried to the battery via a smaller, thinner strip, which saves costs without compromising on performance, according to the company.
