Machining of ring shaped worn pieces
- 1995

Ingår i: Journal of Materials Processing Technology. - 0924-0136. ; 48:1-4, s. 239-245

Tidskriftsartikel (refereegranskat)abstract
- The connection between the tolerances possible to obtain in a machining process and the machining forces and clamping forces in turning of ring-shaped work pieces clamped in conventional chucks with varying jaw numbers has been investigated. The results can be used for adaptive control of the clamping forces in an optimal way so that the work piece does not come loose in the course of machining and the desired tolerances can be obtained.
