Optimum test method for approximation cutting with equal removal amount

Abstract

The invention discloses an equal resection amount approaching cutting optimization test method. The method comprises the following steps: at first, determining a set of basic cutting amounts (Pb) for experiments, using the basic cutting amounts to carry out cutting wear experiments, taking the cutting time when a flank wear (Vb) intermediate value is not greater than 0.3 as the basic cutting time (Tb); according to the maximal range of each cutting amount, determining the range ratio (S) of the cutting amount, wherein normally 1<S<2; according to equal resection amount, determining the experiment cutting amount (P); in order to find the optimal cutting amount without affecting the original production efficiency, picking two of basic cutting amounts, multiplying the two by S and 1 / S respectively, taking the results as the basic cutting amounts, maintaining the cutting time, and determining all possible cutting amount combinations. The test result can directly determine the advantage and disadvantage of each cutting amount combination. The influence caused by inaccurate empirical formula and mathematical model is avoided. Through more experiments, the cutting amount can be continuously optimized, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of machining and optimization tests, and in particular provides a cutting amount optimization test method. Background technique [0002] The existing cutting parameters optimization test methods generally use a series of cutting test results under different combinations of cutting parameters to establish mathematical models by fitting empirical formulas with regression methods. Determine the constraints and optimize the objective function, and finally use algebraic or iterative methods to obtain the optimal cutting amount. [0003] Among them, the cutting amount generally includes the feed amount (milling usually uses the tooth feed amount f z , other processes usually use the feed per revolution f n ), cutting speed V c , Depth of cut a p (for general turning, side edge milling, reaming, boring), cutting row spacing a e (for flank milling). The cutting test generally adopts single factor test method, ...

Problems solved by technology

At the same time, when there is a need to optimize the cutting amount in actual production, the production line and the production cycle have been determined, and the highest profit margin target has also lost the demand

[0010] Usually, only one kind of cutting parameters can be optimized by using the optimization objective function, and multiple cutting parameters cannot be optimized at the same time.

[0011] Based on the above reasons, the application of this cutting amount optimization test method in enterprise production is very limited.

At the same time, there is also a lack of a fast and effective method for optimizing cutting parameters that can be directly applied to the production process of products.
