The determination of the optimizati

The determination of the optimization target should be based on the principle of obtaining the maximum economic benefit in this processing. In production practice, there are three common cutting process optimization goals(a) Maximum productivity (average minimum production time per piece);(b) The lowest cost (the lowest average processing cost per piece);(c) Maximum profit margin.The best quality is not included in the optimization goal. Because generally speaking, the higher the product quality, the better the technical requirements for each specific process. This process only needs to meet technical requirements, and blindly pursuing processing quality will cause unnecessary increase in processing costs and unnecessary waste. Therefore, processing quality is not an optimization goal, but a constraint condition.The most convenient and flexible control factor in the cutting process is to select the process parameters (cutting parameters and tool geometric parameters, forward inclination angle, forward inclination angle, main deflection angle, edge inclination angle, etc.) as the control factor. However, in order to establish an objective function and facilitate analysis, tool life is generally selected as an intermediate control factor. In this way, the objective function becomes a single factor function between the optimization index and the tool life. In order to control the tool life, the process parameters must be controlled, so the relationship between the optimization index and the process parameters is established.
