Virtual Machine Tool 总被引:10,自引:0,他引:10
This paper presents current state of Virtual Machine Tool Technology and related ongoing research challenges. The structural analysis of machine tools using Finite Element models and their experimental calibration techniques are presented. The kinematic analysis and optimisation of machine tool elements are discussed with sample examples. The interaction between the control of the feed drives, cutting conditions and machine tool structure is presented. Multi-body dynamic models of the machine, which allow integrated simulation of machine kinematics, structural dynamics and control techniques, are discussed. The interaction between the machine tool, controller and cutting process disturbances are discussed with sample examples. The simulation of machining operation and its impact on the dynamics of the machine tool and CNC are elaborated. The paper presents both the summary of current and past research, as well as research challenges in order to realise a fully digitised model of the machine tool. 相似文献

Virtual High Performance Milling 总被引:3,自引:1,他引:3
The goal of future manufacturing is to design, test and manufacture parts in a virtual environment before they are manufactured on the shop floor. This paper presents a generalized process simulation and optimization strategy for 2 1/2 axis milling operations to increase Material Removal Rate (MRR) while avoiding machining errors. The process is optimized at two stages. Optimal spindle speed, radial and axial depth of cut are recommended to process planner by considering the chatter, and spindle's torque/power limits. The cutter-part engagement conditions are extracted from CAD system by geometrically processing the NC program and part geometry. Long tool path segments are broken into smaller segments whenever the geometry varies. The spindle speed and feed fields of the NC program are automatically optimized by constraining maximum torque, power, tool deflection and chip load set by the user. The acceleration and speed limits of the machine tool feed drives are considered to prevent frequent variations of the feed unnecessarily. The optimization is experimentally verified by milling a helicopter gear box cover on a high speed, horizontal machining centre. 相似文献

采用密度泛函理论中的虚拟晶体近似方法研究了Zr和Ru掺杂Pd体系的相结构稳定性。搭建了3种可能的虚拟晶体近似模型,并计算了体系的弹性常数正方剪切常数、体模量、剪切模量、杨氏模量、Cauchy压力值和态密度等。计算结果表明根据正方剪切常数判断Pd-5Ru-1Zr[T(3)]是Pd-Ru-Zr体系中最稳定的相,根据Cauchy压力值判断 Pd-10Ru-1Zr[T(2)] 是硬脆相,并且具有较强的方向键,随着Ru和Zr原子逐步替代Pd原子,体系的化学键强度和硬度逐渐增大,但是相结构稳定性有所降低 相似文献
