An Alternate Machining Method for Hardened Automotive Gears

Process Optimization for Machining of Hardened Steels

An alternate method for performing MRTD measurements

The Minimum Resolvable Temperature Difference test (MRTD) is one of the tests typically required to characterize the performance of thermal imaging systems. The traditional test methodology is very time intensive, requiring data collection at multiple temperatures and target frequencies. This paper will present an alternate methodology using a controlled blackbody temperature ramp rate. This al...

On machining of hardened AISI D2 steel with PCBN tools

This paper describes an experimental investigation on machining of a difficult-to-cut material, AISI D2 steel of hardness 62 HRC with PCBN tools. It was found that the most feasible feeds and speeds fall in the ranges 0.08–0.20 mm/rev and 70–120 m/min, respectively and that most of the tested PCBN tools reached the end of life mainly due to flank wear. The highest acceptable values of tool life...

A Reduction Method of Cogging Torque for Magnetic Gears

Nowadays, magnetic gears (MGs) have become an alternative choice for mechanical gears because of their low maintenance, improved durability, indirect contact between inner and outer rotors, no lubrication, and high efficiency. Generally, although these advantages, MGs suffer from inherent issues, mainly the cogging torque. Therefore, cogging torque mitigation has become an active research area....

An alternate method for placement of C-1 screws.

OBJECT Several techniques for the surgical stabilization of the atlas and the axis have been described. Placement of C-1 lateral mass screws is one of the latest technical advances, and has gained popularity due to its efficacy and biomechanical advantages. However, the technique for placement of C-1 lateral mass screws, as first described by Harms, can cause excessive bleeding or irritation of...
