FORCES AND TEMPERATURES IN HARD TURNING

Machining Science and Technology, 2006
In precision machining, due to the recent developments in cutting tools, machine tool structural rigidity and improved CNC controllers, hard turning is an emerging process as an alternative to some of the grinding processes by providing reductions in costs and cycle-times. In industrial environments, hard turning is established for geometry features of

Turning and Grinding of Hard Alloys

Advanced Engineering Materials, 1999
Hard alloys count among the hard-to-machine materials. Performance characteristics such as high hardness and wear resistance as well as the structural difference between hard phases and metallic matrix impede their machineability. The authors review the effects of the mechanical and thermal energy exerted by turning and grinding processes on the ...

Surface Integrity in Hard Turning

2003
Highly-stressed steel components, e.g. gears and bearing parts, are appropriate applications for hard turning. Therefore the process effects on significant engineering properties of work materials have to be carefully analyzed. Roughness, residual stresses and white layers as parts of surface integrity, are function of the machining parameters and of ...

Hard Turning with PCBN Tooling

1999
Material removal, at economic rates, from hardened workpieces has always presented a challenge and, until quite recently, abrasive machining processes were the only option for hard-facings. However, cutting tools based on polycrystalline cubic boron nitride (PCBN) have opened up the possibility of turning and milling as attractive alternatives for ...

Roller burnishing of hard turned surfaces

International Journal of Machine Tools and Manufacture, 1998
Abstract In a hard roller burnishing operation, a hydrostatically borne ceramic ball rolls over the component surface under high pressures. The roughness peaks are flattened and the quality of the workpiece surface is improved. When combined with hard turning, this process provides a manufacturing alternative to grinding and honing operations.

Hard drive technology reaches a turning point

Computer, 2003
Hard-drive technology is at a critical point in its history. Vendors are hitting limits on the amount of data that current technology can read and write on a square inch of disk space. While hard drive capacity will continue to increase, the rate of areal-density growth will likely slow.
