Titanium alloys are difficult-to-machine materials that exhibit a low machining efficiency, yielding its restricted applications. The combination of micro-textures and cemented carbide surface cutter can effectively improve the cutting performance enhance titanium alloys' quality. Therefore, this manuscript investigates ball-end milling with modifications. Firstly, we prepared variable distribution density on revealed properties from microscopic aspect based simulation test methods....
A high temperature is produced in the process of precision milling titanium alloy, and cutting can be effectively reduced by placing a micro-texture on tool surface. In order to study micro-textured ball-end cutter alloy under combined action blunt radius with different edges parameters, new method based micro-element theory generation transmission heat has been established. At same time, influence radii simulated finite element experimentally verified explore edge parameters temperature....
When precision cutting titanium alloy, the part of tool is mainly concentrated in edge area, so there a strong emphasis upon edge’s geometric parameters. Studies have found that putting micro-texture on surface can reduce force. This article looks at milling force involved alloy with micro-textured ball-end cutter different shaped edges. First, model relating to edges established based traditional Then, effects geometry parameters and are simulated tested using finite element method. With...
This experimental study presents the rheological properties and strength characteristics of cemented unclassified tailings backfill (CUTB). The particle size distribution chemical from Shizhuyuan lead-zinc mine were examined experimentally. A series uniaxial compressive (UCS) tests conducted to relations between CUTB two factors cement-tailings ratio (c/t) solid content (SD). two-factor nonrepetitive analysis variance (ANOVA) method was used sensitivity c/t SD. Relations UCS performance c/t,...
In order to optimize the position of micro-texture on negative chamfering edge ball-end milling cutter, experiment titanium alloy with cutter was carried out. The effects at different placement positions (rake and flank faces cutting tools) performance were compared when depth 0.3 mm, parameters studied. Finally, optimized based genetic algorithm. results show that face can improve performance, angle width have greatest influence performance. parameter optimization are: is 10.016°, 199.995...
When machining titanium alloy parts, aside from accuracy, the other key concern when evaluating their quality is integrity of machined surface. Residual stress can have a significant impact upon this. A certain amount residual help to strengthen workpiece, but excessive lead its deformation. In this paper, we report on an experimental study surface after milling with microtextured ball-end cutter. Tests were conducted assess stresses workpieces according direction feed and milling. The...
The microstructures and properties of (Tb,Sm)CoSi/Cr series films have been investigated. All the samples were sputtered annealed at 500 °C for 25 min in pure N2 atmosphere, their examined. effect on magnetic partial Sm substituted by Tb is discussed. lattice matching media And mechanisms interactions among grains between layers analyzed comparing multi layer with mono layer.
Abstract Contact calculation is of great importance in predicting the material removal (MR) flexible grinding process (FGP). The contact mostly considered approximately constant existing MR models, while situations that varies a lot after FGP are ignored. Therefore, novel model proposed this paper to take those into consideration. Firstly, nonconstant-contact situation introduced. Then an equivalent method developed convert accumulation several quasi-constant-contact processes. Based on...
In a planar pushing operation, particularly at higher velocities, the object's inertia can not be ignored. This paper so determines dynamics aspect of mechanics for case four-points support. If is neglected in high-speed pushing, object translates along line. However, when considered, there tendency to rotate.
