The purpose of our study is to investigate the heat distribution and the occurring temperatures during grinding. Therefore, we did both experimental and numerical investigations. In the first part, we present the integration of an infrared thermopile array in a steel workpiece. Experiments are done by acquiring data from the thermopile array during grinding of a groove in a workpiece made of st...

A transient two-dimensional model is developed and numericaUy solved to specifically investigate the effects of CNC motion and workpiece boundary on cutting front mobility and temperature in reactive-gas assisted C01 laser cutting. Co-ordinated motion systems must ramp up and down to their desired speeds, and therefore the initial actuator acceleration is considered for its effect on the cuttin...

In this investigation, experiments were carried out to understand the influence of various grinding parameters like wheel speed, workspeed and depth of cut on the grinding temperature at the surface of the Al-SiCP composite workpiece with different grinding wheels. The temperature distribution within the workpiece was studied by simulating the grinding process and using finite element analysis ...

This paper contains novel model using feedback neural networks for a work piece temperature prediction. The heat and mass transfer in a porous metal workpiece which is heated by a fire gun is studied. The heat flux distribution is determined by thermocouple connected on the workpiece at definite distances. The gun work piece distance were also change and the temperature distribution and heat fl...

Abstract. A finite element model is proposed for the simulation of grinding of hardened steels with aluminium oxide wheels. For this task the implicit FEM code MARC is used. The proposed model is a transient state, non-linear problem that can calculate the maximum temperature and the temperature fields on the ground workpiece. The input data required for the analysis are provided through a seri...

Friction drilling uses a rotating conical tool to penetrate the workpiece and create a bushing in a single step without generating chips. This research investigates the threedimensional (3D) finite element modeling (FEM) of large plastic strain and hightemperature work-material deformation in friction drilling. The explicit FEM code with temperature-dependent mechanical and thermal properties, ...

Ultrasonic testing is a versatile and important nondestructive testing method. In many industrial applications, ultrasonic testing is carried out at relatively high temperatures. Since the ultrasonic w...

An incrementally coupled electrical – thermal – mechanical model is developed to simulate small scale resistance spot welding (SSRSW) using the finite element method. This numerical model is then employed to study the differences between SSRSW and ‘large scale’ resistance spot welding (LSRSW). The variations in contact area, current distribution, and temperature profile at the workpiece/workpie...

Thermal load in manufacturing processes is of special interest as it is closely connected with the surface integrity and life-cycle of the finished product. Especially in grinding, heat affected zones are created due to excessive heat dissipated within the workpiece during the process. In these zones, defects are created that undermine the quality of the workpiece and as grinding is a precision...
