| dc.description.abstract | This study was to improve the traditional free-abrasive wire saw machining,due to the abrasive doesn’t completely will immediately cutting debris andrefining discharged.High abrasive waste so that the required processing time of growth on the wire saw, the relative costs to be incurred higher shortcomings toimprove. In this study, the evelopment of composite plating nickel - diamond coated to the piano wire, the research study of piano wire itself cutting of the tool, hoping to effectively improve the traditional free-abrasive sawing, therebyreducing the cost of the process.
The study divided into two parts, the first part of the preparation of piano wire: nickel - diamond composite lating solution to plating coated on the piano wire. Experimental results show that, with the increase of current density and plating time, the coating thickness increases. Current density of 7 A/dm2 and diamond concentration of 100 g/L, the parameters of the plating experiments, piano wire has a better coating thickness and diamond coated. The second part of the Taguchi experimental design for high-speed steel cutting, explore the impact of various parameters on the depth of cut. From the experimental results, better process parameters combination: Cutting load 500 g, workpiece rotation 3000 rpm, feed rate 3.5 mm/min, thread tension 1500 g, co-deposition time 10 min, current density 7 A/dm2 and diamond concentration 100 g/L for cutting, cutting depth up to 27.01 μm.
