The compensation of geometrical errors on forming grinding

Journal of Materials Processing Technology, 1998
Form grinding produces a surface with a particular profile. In a plug-grinding system, the shaped wheels transfer their profile to the ground work surface. Several factors affect the geometrical errors that occur in grinding, including thermal deformation, the cutting forces of the workpiece and the wear and the plastic deformation of the grinding ...

Electrochemical grinding of ceramic form tooling

Journal of Materials Processing Technology, 1995
Abstract This research investigates the process of electrochemical grinding (ECG) when used to machine metal-bonded diamond composite wheels. These wheels are used as form tools to grind ceramics. The wheels have to be machined to form and to tight tolerances, in good time.

Peripheral Electrochemical Grinding with a Formed Wheel

1973
An important application of electrochemical grinding is component production using a formed wheel. The paper presents an introduction to features peculiar to a peripheral configuration and discusses some experimental results obtained when machining a trapezoidal slot in Nimonic 105 using NaNO2 aqueous electrolyte solution and a Norelek formable wheel ...

Simulation and Optimization of Gear Form Grinding

Volume 6: ASME Power Transmission and Gearing Conference; 3rd International Conference on Micro- and Nanosystems; 11th International Conference on Advanced Vehicle and Tire Technologies, 2009
Nowadays, the basic requirements of gear transmissions are not limited only to the more usual ones (like resistance, reliability ...), but often include also good efficiency and low vibration and noise emissions. Supporting structures, gear macro and micro geometry and textures are the key-points in the design of a geared system that fulfil the latter ...

Wheel-Workpiece Conformity in form Grinding

1979
The conformity of fit between a grinding wheel and a workpiece is defined in terms of the curvature difference between the appropriate adjacent wheel and workpiece surfaces. Both static and dynamic conformities of fit are considered and it is shown that the two are simply related.

Wheel-Wear Compensation for Numerical Form Grinding

Journal of Engineering for Industry, 1986
A new method for reducing the effect of grinding wheel wear on workpiece inaccuracy in numerically controlled form grinding of surfaces of revolution is proposed and analyzed. A mathematical model to describe wheel wear and contour production is developed for the grinding of a cyclindrical surface.

Form Grinding by Mechanical and Optical Methods

Proceedings of the Institution of Mechanical Engineers, 1950
Methods of producing profile tools and gauges remained for many years particularly conservative and often expensive in the use of highly skilled toolroom labour. Up to comparatively recent times it was not uncommon to find high-class machine tools, such as jig boring machines, applied to the task of marking out centres of radii and so on, because ...

Effect on Grains Form on Performances Grinding Wheels

Applied Mechanics and Materials, 2014
Efficacy of existing designs grinding wheels is relatively low and one of the main reasons for this situation is the lack of control over the shape of grains included in the composition of these tools and their employees cutting elements. Standard wheels are composed of grains with an arbitrary, varying in the range from isometric to the needle-like ...

Analysis on the Temperature Field of Gear Form Grinding

Applied Mechanics and Materials, 2014
Aiming at the issue on grinding burn of tooth face, the temperature field formed in helical gear form grinding was analyzed. The finite element model of the single tooth of helical gear was firstly established. Considering the nonlinear relation of the physical properties of gear material to temperature, 3D finite element simulation of transient ...

Economic Analysis of the Helical Form Grinding Process

2017
There would be real benefit to industry should an efficient and economic appraisal methodology be established that can be carried out on a standard and commonly available grinding machine that would allow independent assessment of grinding process variables and technologies and provide industrial users with the data that they need for process ...
