Analysis of intermittent grinding phenomenon in cylindrical traverse grinding.

Study of Traverse Grinding Process (1st Report) Accumulation Phenomenon and Size Generation Mechanism in Traverse Grinding

plicated processes on the wheel surf ace along the wheel width. In order to make these processes clear, the experimental analysis of traverse grinding was conducted by widely changing the speed ratio, Kv, the setting depth of wheel, ‡TMT, and the number of total steps, m, (the ratio of the wheel width over the traverse feed per one revolution of the workpiece). The following results were obtain...

Realisation of grinding-hardening in workpieces of curved surfaces—Part 1 Plunge cylindrical grinding

This paper investigates the feasibility to achieve grinding-hardening in a plunge cylindrical grinding process. To understand the mechanisms, a temperature-dependent finite element heat transfer model incorporating a triangular moving heat source was developed to describe the temperature field, thus to predict the thickness of the grinding-hardened layer. The analysis carried out included the v...

Effect of vitrified bond microstructure and volume fraction in the grinding wheel on traverse internal cylindrical grinding of Inconel alloy 600

The following article examines the influence of glass-crystalline bond in grinding wheels with grains made from microcrystalline aluminum oxide, and specifically its effect upon the values of selected operational indicators in the process of traverse internal cylindrical grinding of surfaces made from Inconel® alloy 600. The experimental test results obtained showed that changes in the bond pha...

Synthetically Modeling of Thermal Error and Grinding Force Induced Error on a Precision NC Cylindrical Grinding Machine

Thermal errors and force-induced errors are two most significant sources of the NC grinding machine inaccuracy. And error compensation technique is an effective way to improve the manufacturing accuracy of the NC machine tools. Effective compensation relies on an accurate error model that can predict the errors exactly during machining. In this paper, a PSO–BP neural network modeling technique ...
