Uncertainty of the Measurement of Radial Runout, Axial Runout and Coning using an Industrial Axi-Symmetric Measurement Machine
This paper describes an uncertainty evaluation for the measurement of radial runout, axial runout and coning for axisymmetric measurement machine. An industrial axi-symmetric measurement machine was used which consisted of a rotary table and a number of contact measurement probes located on slideways. Type A uncertainties were obtained from a repeatability study of the probe calibration process...
متن کاملContinual induction hardening of axi-symmetric bodies
The paper presents a methodology of computer modelling of continual surface induction hardening of axi-symmetric bodies. The body is heated by a cylindrical inductor moving at a given velocity along it and the heated part is then cooled by spraying water. While the mathematical model of induction heating is given by two partial differential equations describing the harmonic electromagnetic and ...
متن کاملOn the Cauchy problem for axi-symmetric vortex rings
We consider the classical Cauchy problem for the 3d Navier-Stokes equation with the initial vorticity ω0 concentrated on a circle, or more generally, a linear combination of such data for circles with common axis of symmetry. We show that natural approximations of the problem obtained by smoothing the initial data satisfy good a-priori estimates which enable us to conclude that the original pro...
متن کاملAnalytical Modeling of Axi-Symmetric Sheet Metal Forming
The cup drawing is a basic deep drawing process. Thus, understanding the mechanics ofthe cup drawing process helps in determining the general parameters that affect the deep drawingprocess. There are mainly two methods of analysis; experimental and analytical/numerical.Experimental analysis can be useful in analyzing the process to determine the process parameters thatproduce a defect free prod...
متن کاملHigh order quadratures for the evaluation of interfacial velocities in axi-symmetric Stokes flows
Boundary integral methods have been used widely for the simulation of interfacial Stokes flows. These free surface representations reduce the problem to one defined solely on the fluid interface. Often the assumption of axi-symmetry is used to further reduce the dimensionality of the problem. However, it is difficult to obtain high order approximations to the resulting line integrals due to the...
