Oct 24, 2018 The purpose of this article is to demonstrate the calculation of wheel life in creep-feed grinding. Calculating wheel life is essential for forecasting wheel usage and the abrasive costs associated with a grinding process. In order to calculate the wheel life, it is essential to know which dressing methodology is being used.

Apr 11, 2017 The centerless process is commonly used for high volume production, and it’s also easily used for low volume production because the machine setups are fairly simple. In thrufeed centerless OD grinding the workpiece passes between two wheels, a grinding wheel and a regulating wheel (as illustrated in the diagram, right).

Jan 01, 2007 Based on this work, the author has successfully developed the GrindSim software to set-up and optimise cylindrical grinding processes. Two possible criteria can be used to design a centerless grinding cycle: 1) Minimise the process cycle time or 2) Adjust the cycle to a previously established process time, minimising wheel wear.

Centerless grinding is a machining process that uses abrasive cutting to remove material from a workpiece. Centerless grinding differs from centered grinding operations in that no spindle or fixture is used to locate and secure the workpiece; the workpiece is secured between two rotary grinding

In centerless grinding, the workpiece is held between two grinding wheels, rotating in the same direction at different speeds.One grinding wheel is on a fixed axis and rotates so that the force applied to the workpiece is directed downward. This wheel usually performs the grinding action by having a higher linear speed than the workpiece at the point of contact.

This work presents a method to optimize centerless grinding geometrical configuration. It is based on the regulation of the horizontal axes of operating and regulating wheels of the machine, coupled with an opportune blade profile, allowing a continuous selection of workrest angle and workpiece height, without requiring blade substitution and/or manual interventions.

However, the cycle time in spark-out grinding process is not easy to be estimated. From such a viewpoint, in this study, using specific grinding force obtained by measured grinding force in the first spark-out pass, a calculating method of the real ground depth in continuous pass process is proposed. And, this method is experimentally evaluated.
