The importance of temperature in grinding

Journal of Mechanical Working Technology, 1988
Abstract The entire field of grinding may be divided into stock removal grinding (SRG) that involves relatively large chips and no need for dressing and form and finish grinding (FFG) that involves small chips and the need for periodic dressing of the grinding wheel.

Heat Partitioning and Temperatures in Grinding

Manufacturing Science and Engineering, 1996
Abstract A theoretical analysis is presented of the energy partitioning and surface temperatures in grinding. The numerical results agree with the experimental results of Kohli et al. It is found that the presence of the fluid inside the grinding zone can reduce the heat flux into the workpiece and the workpiece temperature significantly.

On the measurement of surface grinding temperature

International Journal of Machine Tool Design and Research, 1981
Abstract A sandwiched thermocouple technique was developed to measure the grinding temperature. This technique has the advantage over the wheel-work thermocouple method developed previously as individual calibrations are not required when different workpieces are used. In order to account for the thermal inertia effect of the thermocouple junction, a

Temperature control in CBN grinding

The International Journal of Advanced Manufacturing Technology, 1996
The main advantage of CBN grinding wheels is the long wheel life owing to the hardness of the CBN abrasive. Recent research has confirmed another advantage of CBN, which is cooler grinding. The new research allows the temperature in grinding to be predicted based on experimentally validated CBN thermal properties. This work also provides for in-process

Analysis of Transient Temperatures in Grinding

Journal of Engineering for Industry, 1995
Temperatures generated in the workpiece during straight surface plunge grinding follow a transient behavior as the grinding wheel engages with and disengages from the workpiece, and throughout the entire grinding pass for workpieces which are shorter than needed to reach a quasi-steady state condition. In the present paper, a thermal model is developed

Temperature Field Analysis in Grinding

2019
The paper is devoted to solving an important scientific problem of determining the profile grinding temperature based on the choice of a not complex but at the same time adequate solution from the available analytical ones. The initial prerequisite for the paper developing concept is that of a moving heat source. In engineering applications, the moving

Understanding the Temperature Field in Plunge Cylindrical Grinding for Grinding-Hardening

Key Engineering Materials, 2010
This paper investigates the temperature field in plunge cylindrical grinding with the aid of the finite element analysis. The analysis included the effect of the variation of the depth of cut and that of the repeated heating and cooling caused by workpiece rotation.

An Investigation of Temperatures in Form Grinding

2000
The temperature rise experienced by the workpiece during grinding may be calculated with reasonable confidence for simple shapes: cylindrical and plane surfaces. In the case of more complex forms, the thermal analysis must account for non-uniform temperature distributions that result from variations in contact conformity and material removal rates ...

Automatic Control Technology of Grinding Zone Temperature in Grinding Hardening

Advanced Materials Research, 2011
In grinding hardening process, part’s surface (grinding zone) temperature directly affects the quality of surface layer of heat treatment. The high temperature heat pipe is very good device of control heat transfer. In order to make the grinding zone temperature slightly change in grinding process, this paper describes a design of temperature automatic
