“…The flow chart of the simulation analysis model, which implements the 2D simulation optimization, is shown in Figure 7. The 2D milling model was constructed in ABAQUS and the parameter optimization of the bionic collinear was achieved through an interface between this software and Python [23]. Compiling the complete Python script program and running the script in ABAQUS can greatly reduce the number of times the milling model is built and automate the modeling.…”

：Bionic design of cutting tools to reduce working resistance and energy consumption has always been a concern of people.The curve of the rake face of beaver teeth is fitted and its general expression is obtained. The function is used in the configuration design of the bionic alignment of the front cutter face of cylindrical milling cutter, and the bionic curvilinear configuration rake face cylindrical milling cutter is designed. By constructing a three-dimensional milling simulation model of a cylindrical milling cutter, the cutting performance of a cylindrical milling cutter with a bionic collinear configuration and a cylindrical milling cutter with a flat front face was analyzed by comparing the milling simulation with a cylindrical milling cutter with a bionic collinear configuration composed of different combinations of front face collinear parameter values. The results show that the designed bionic collinear configuration front face cylindrical milling cutter exhibits certain force saving effect and is verified by right angle free cutting experiments, but its drag reduction performance is affected by the parameter values of the collinear. The optimized parameter values of the front face collinear of the tool with a certain side draft are obtained by genetic algorithm combined with finite element simulation analysis, and the optimal combination of collinear parameter values is obtained. Key words：Cylindrical milling cutter； Bionic design； Finite element simulation； Milling force； Optimization of tool geometric parameters 0 Introduction *1According to statistics, in metal cutting, the energy consumed by the metal workpiece after plastic deformation into chips accounts for more than 70% of the total energy consumed [1], and most of this energy is converted into heat and dissipated. Therefore, reducing some unnecessary energy losses while machining metal workpieces and improving the cutting efficiency of metal cutting tools is a meaningful and worthwhile research problem in the current environment [2][3][4].Cutting requires three necessary conditions, the tool for cutting, the workpiece to be machined, and the cutting motion between the tool and the workpiece [5]. From a bionic point of view, there are cutting processes similar to it in nature. The teeth, claws and toes of some animals in nature, as well as the leaves of plants and other parts are equivalent to the tools used for cutting, trees, soil and stalks of crops can be equivalent to the workpiece being processed, and the behavior of animals gnawing trees and digging soil can be seen as the cutting movement between the tool and the workpiece.The contours of the teeth, claws and toes, and leaves of these plants and animals are generally geometric configurations that contain some special shape features, which have evolved over billions of years and have their own intrinsic biomechanical mechanisms [6][7][8]. New cutting tools designed by using the special contour shape of these animal teeth and claws and toes usually exhibit excellent friction and d...

The Shaping of a Gender Norm: Marriage, Labor, and Foot‐binding in Historical China

This article presents a theory that explains the rise of foot‐binding in historical China, in response to a gender‐asymmetric social mobility shock that dispersed men's quality distribution in the marriage market. The theory characterizes the marriage market equilibrium and women's competition strategies before and after the shock. Empirical evidence using archival data corroborates the theoretical predictions that greater men's social mobility opportunities encouraged foot‐binding and that a greater cost of women's labor discouraged foot‐binding. The article thus highlights that costly gender norms can be traced back to gender asymmetry in social mobility opportunities.
