Study on the Matching of Surface Texture Parameters and Processing Parameters of Coated Cemented Carbide Tools

Placing micro-textures on a tool surface can play an anti-wear and friction-reducing role capture impurities improve the tool-chip friction state, thus improving cutting performance of quality workpiece. To ensure processing in micro-texture-coated tool-cutting process, process parameters micro-texture are limited to smaller parameters, which reduces efficiency increases cost. Aiming at this problem, paper designs orthogonal experiments builds experimental platform for milling titanium alloy with ball-end cutter, analyzes influence workpiece quality, establishes high fitting prediction model, optimizes parameters. The results show that significantly affect force, wear, roughness, first response level, second level. It is proven has anti-friction effects, it found evaluation index by changing distribution state micro-texture. multiple linear regression model fits better. Parameter optimization are: v = 159.4232 (m/min), ap 0.211 (mm), f 0.06 (mm/r), micro-pit diameter D 62.3429 (?m), distance from blade L 121.5184 spacing L1 235.6443 (?m). provides some guidance selection tool.
