Identification of cutting errors in precision hard turning process
Journal of Materials Processing Technology, 2004 During past 10 years, the availability of polycrystalline cubic boron nitride (PCBN) tools has made application of hard turning increase remarkably in a range of industrial areas, especially in automotive, roller bearing and hydraulic industry. Among the

Journal of Superhard Materials, 2009
The results of the comprehensive studies of a highly efficient method of finishing, the so-called hard “skiving” turning, are discussed. Special features of the oblique cutting with a tool equipped with cBN-based polycrystalline superhard materials are shown, the regularities of the surface roughness formation and surface layer hardening in machining ...

Advanced Materials Research, 2013
Hard turning is a turning operation performed on hard materials (hardness more than 45 HRC) in order to reach surface roughness close to that obtained in grinding. The development of this technology was accompanied by the development of new cutting materials such as cutting ceramics, cubic boron nitride and polycrystalline diamond.

FORCES AND TEMPERATURES IN HARD TURNING
Machining Science and Technology, 2006In 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, 1999Hard 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 ...

Hard Turning with PCBN Tooling
1999Material 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 ...

Surface Integrity in Hard Turning
2003Highly-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 drive technology reaches a turning point
Computer, 2003Hard-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.

Evaluation of the Stability During Hard Turning
2006There are several indicators which could confirm assumption of turning instability (depth of cutting, high ratio of forces Fc/Fp, small tool nose radius, and non-uniform stress distribution over tool/workpiece contact). These indicators can be monitored during turning process (forces, vibrations, sound, etc.) or after process has been finished ...
