Adaptation of Traditional Grinding Force Models to Cylindrical Cup Grinding
Optical Fabrication and Testing, 1996The dynamics of grinding is less well investigated than other machining processes. In particular, the cylindrical cup grinding process used in optical manufacturing has received little attention. Our interest in this arises from the observation of rose-petal shaped marks called cutter marks during microgrinding glass lenses.

Tribology International, 2019
Abstract This study presents a numerical model of the grinding force during rail grinding that considers the influence of the swing angle of the grinding stone on the position of the grinding area. The numerical model of movement process and material removal of single abrasive grain at different swing angles are established.

International Journal of Abrasive Technology, 2016
In the present paper, a semi-empirical grinding force model is developed combined with the achievements of previous researchers by composing effects of normal and tangential grinding forces in two main parts respectively: cutting force and sliding force. This model is used to predict the total normal and tangential force in the surface grinding.

Grinding Force Model for Low-Speed Grinding Based on Impact Principle
Advanced Materials Research, 2013In the low-speed grinding process, the force generated when the wheel grinding the workpiece is the result of sliding friction, plough and cutting. While in the actual study, the cutting process has attracted extensive attention. Impact effect to the entire grinding process on the contact is ignored so that the error exists between the calculation ...

Modeling of Grinding Force in Constant-Depth-of-Cut Ultrasonically Assisted Grinding
Materials Science Forum, 2004This paper discusses the mechanism behind the grinding force decrease associated with ultrasonication of the grinding wheel in constant-depth-of-cut ultrasonically assisted grinding (UAG). By introducing a grinding model describing the cutting trace of an abrasive grain, an equation relating the grinding force decrease to such process parameters as the

Force Modeling for Cup Wheel Surface Grinding
Manufacturing Science and Engineering, 1998Abstract This paper describes the development of a model for the forces in surface grinding with a cup wheel. The model incorporates the considerations of material removal from the front end of the wheel, the velocity differential between the wheel and part, the material removal from the bottom contact surface of the wheel, to deflection

A New Approach to Development of a Grinding Force Model
Journal of Engineering for Industry, 1987A theoretical model has been developed for representing the grinding forces. This is based on the fact that the chip formation during grinding consists of three states: ploughing, cutting, and rubbing. Expressions for the total normal and tangential force components during these three stages were established. These components were expressed in terms of

A grinding force model for ultrasonic assisted internal grinding (UAIG) of SiC ceramics
The International Journal of Advanced Manufacturing Technology, 2015As grinding force plays an influential role in work-surface finish in grinding process, a model is necessary for optimizing input variables to achieve high product quality and productivity. However, to the best of our knowledge, there are few reports on modeling grinding force in ultrasonic assisted internal grinding (UAIG).
