The application of Taguchi approach to optimise the processing conditions on bonnet polishing of CoCr alloys

چکیده
This paper applied the Taguchi approach to investigate the effects of polishing parameters to obtain the optimal processing conditions for CoCr alloy polishing using a multiaxis CNC controlled corrective polishing machine. The polishing medium used was 1m diamond paste with a Microcloth(polishing cloth). Surface finish parameter Sa was chosen as the criterion for process optimization. The experimental results indicate that the optimal polishing conditions for CoCr alloy polishing is 5 precess angle, 800 rpm head speed, 0.2mm tool offset and 1.5 bar tool pressure. With this optimal condition, a confirmatory experiment was conducted. The surface roughness Sa reduced from an initial 24nm to 7nm and reduction ratio was 70.8% which was very close to the estimated ratio of 64%.

متن کاملThe investigation of material removal in bonnet polishing of CoCr alloy artificial joints
In the process of form control using bonnet polishing an influence function is of vital importance for establishing material removal rates. However, the effects of polishing cloth, workpiece hardness and polishing parameters (such as precess angle, head speed, tool pressure and tool offset) on influence function when polishing CoCr alloys are not yet established and these factors affect the det...
متن کاملInvestigation of the material removal characteristic for polishing CoCr alloy
To investigate the material removal characteristic of paste polishing, experimental investigations based on Taguchi method have been carried out. In the experiments, the dwell time was fixed 300 seconds and the bonnet position was 4. The four variable factors (precess angles, head speed, head pressure and tool offset) with 3 levels were chosen to design the orthogonal array. With the designed o...
متن کاملDevelopment of precision polishing machine based on hexapod
Increasing demand on mass production of high precision parts, has pushed the precision manufacturing industry to develop relatively low cost, reliable precision finishing processes to meet market requirements. A gap within the provision of low cost polishing processes has been identified; namely parts with a radius of curvature less than 10mm will be increasingly present in new mass produced pr...
متن کاملApplication of Taguchi design for optimization of corrosion behavior of amorphous silica thin film deposited through sol-gel dipping technique
Amorphous silica thin films were applied on the 316L stainless steel substrates by sol-gel dipping technique. The starting chemicals (TEOS, ethanol, HCl, PEG, and NaOH) were used to prepare a gel and then deposited on a substrate. The microstructure, topography, corrosion behavior, and surface hardness were investigated using SEM, AFM, electrochemical method, and micro-hardness measurements. Th...
