A Finite Element Analysis for the Characteristics of Cutting Parameters in 3D Oblique Milling Process

Abstract

In the field of aeronautical and astronautical manufacturing, milling is a basic machining process by which a surface is generated by progressive chip removal. Therefore, this paper reports a complete procedure of the finite element model for the 3D oblique milling process using the commercial software package ABAQUS. Effect of various parameters on cutting forces is mainly discussed. The model correctly exhibits the observed transition from small to large force with increasing cutting speed and cutting depth.

Numerical simulation study on stress field distribution of die-cutting machine under no-load condition

“…The working principle of the fully automatic flat die cutting machine is that the electric motor drives the flywheel and worm gear through an electromagnetic clutch (or pneumatic clutch) to transfer power to the crankshaft. Then, the crankshaft acts on the connecting rod mechanism and elbow arm (up and down swing rods), known as the elbow rod, converting the rotational motion of the motor into vertical motion, thereby driving the moving platform to achieve reciprocating activity [6]. During the paper conveying process, the paper feeding component feeds the paper into the front and side gauges for positioning, and then the paper is sent to the die-cutting mechanism for secondary positioning by the teeth.…”

Research on Vacuum Sling Technology of Aeronautical Aluminum Alloy Low-Rigid Parts

“…In the hoisting process of aeronautical low-rigid parts ,the number of it is large and there are many kinds.Therefore, it is important to design light self-heavy, big ability of hoisiting,small attrition,long life and saving energy slings.There are two kind ways in hoisting aircraft low-rigid parts parts:one kind is to make bolt hole rings lifting:another kind is to make sling bounding.But with the large -scale of aircraft low-rigid parts,these ways are time consuming and easily make low-rigid parts attrition while using them [1][2][3].…”

Simulation of End Milling for Weak-Rigidity Structural Parts of Aluminium Alloy in Aviation

“…Nowadays, in order to better study simulation of cutting, Qin et al [1] studied cutting speed, cutting depth on cutting force of law. Lin [2] studied the rake angle on cutting force of law.…”
