Mechanical Analysis of Warm Extrusion Precision Forming on 42CrMo Steel Cutting Pick Chunjian Su 1,a, Quanlan Li 1,b,Linjing Xiao 1,c and Sumin Guo 1,d 1 College of Mechanical and Electronic Engineering, Shandong University of Science and Technology, Qingdao 266510, China asuchunjian2008@163.com, bliquanlan1234@163.com, cxiaolj2008@126.com, dgsmwb2006@tom.com Keywords: Cutting Pick, Warm Extrusion, Precision Forming, Extrusion Force.
By former technics, the property of products is poor, and by latter, the material availability is low and the cost is high.
Currently, compared with foreign high-quality pick (German pick), the life of domestic cutting pick is only 1 / 3, which caused a huge waste of valuable raw materials (carbide and steel), and would make device no run continuously, which caused greater economic losses.

The research on warm extrusion process of metal material [M].

The control system model of a three-dimensional elliptical vibration cutting is established, then, the crosstalk data is assumed, using the least squares method to fit the date, crosstalk compensation algorithm is obtained so that the crosstalk removal module can be designed to remove the crosstalk generated the piezoelectric movement ,the final section is the simulation-based analysis, the simulation results show that the method can meet the control requirements of the three-dimensional elliptical vibration, the crosstalk of piezoelectric movement can be removed effectively. 1 Introduction Information transmission equipment and device, such as laser holographic elements, LCD screen and optical waveguide, should employ High- Precision optical components, however, the High- Precision optical components, which always is brittle hard materials, should adopt diamond turning[1]. 3D elliptical vibration cutting is an emerging method of diamond cutting, which is effective method of cutting complex

Nowadays, many researchers have been studying how the existing inorganic semiconductor materials to replace expensive organic semiconductor materials in electronic devices, including the study of organic solar cells.
In addition, these materials with strong absorption efficiency can also be introduced in the device structure, to use these materials absorb some of the energy of sunlight, and then to transfer it to the active material through exciton diffusion.

Principal Outcomes of the EC Thematic Network on Modelling Tools for the Forging Industry Christopher S Kirk 1, Alan N Bramley 2 1, PhD, Senior Researcher, Dept. of Engineering and Applied Science, University of Bath, UK 2, PhD, Professor, Head of Department, Dept. of Engineering and Applied Science, University of Bath, UK Keywords: Forging, simulation, modelling.
By exploiting the case study material from the industrial partners in the Network it has been possible to evaluate these different techniques.
Cluster 3 - Work-piece properties Vital input data for simulation is the stress-strain-strain rate-temperature characteristic of the workpiece material.
Many of the simulation packages have libraries of material data that can be drawn down into the simulation but there is uncertainty over their accuracy.

Fig.2.1 Planar graph Fig.2.2 Cutaway view Numerical simulation analysis 4.1 The assumptions (1)The layer was horizontal distribution, the soil and pile body were isotropic material
It was Better to simulate the artificial boundary.Change the cushion layer thickness of the same material,the settlements of the different stiffness composite foundation were also different. 3) From the calculation analysis with vibration frequency.The vibration frequency was calculated by using spring damping boundary model.The data was more close to the practical situation.
