Abrasive Jet Polishing and its Applications in Surface Finishing
Problem statement: Single Point Diamond Turning (SPDT) is highly deterministic and versatile in producing various forms of precise optics. A typical example is the production of large offaxis aspheric mirrors and various infrared mirrors and mandrels. However, the fine periodical turning marks left in the surface critically limit its performance and they are difficult to be avoided for traditio...
متن کاملDuctile behavior of optical glass in single point diamond turning
Single point diamond turning tests were carried out on a B270 type glass. Submicrometer cutting conditions were applied in order to generate ductile response during single point machining. The profile generated by the rapid removal of the tool tip from the machined surface, analyzed by atomic force microscopy, showed that the brittle-to-ductile transition occurs at a few tenths of micrometers. ...
متن کاملSingle Point Diamond Turning of CVD coated Silicon Carbide
Scratching experiments, using diamond styli and single point diamond tools, were performed to simulate Single Point Diamond Turning (SPDT). The results of these experiments were used to determine if a ductile response is possible, and then to determine the critical depth of cut or penetration depth for the ductile to brittle transition (DBT). The depths of the scratches produced at different lo...
متن کاملModeling of Polishing Mechanism in Magnetic Abrasive Polishing
Magnetic Abrasive Polishing (MAP) is a super-finishing process primarily used for polishing of nonmagnetic and hard materials like, ceramics and stainless steel. This paper deals with the detailed parametric study in polishing of stainless steel work surface. Statistically designed experiments based on Taguchi methods show that size-ratio, tool-work surface clearance, polishing speed, magnetic ...
متن کاملAbrasive Flow Polishing of Micro Bores
This report shares the feasibility study results of abrasive flow polishing of microbores of size φ500 μm or smaller and 25∼50 in aspect ratio for both metal and ceramic materials. A polishing device was designed and built up so as to create enough turbulence for facilitating the polishing at the inner walls of the micro-bore. Polishing of micro-bores on 3 materials: S45C, SS304 and Zr2O3 of le...
