Microscopic Wear Characteristics of Ceramic Grinding Wheel in Creep Feed Grinding

International Journal of Automation Technology, 2022
This paper deals with the microscopic wear characteristics of ceramic (Seeded Gel, SG) grinding wheels used in creep feed grinding. Creep feed grinding experiments with SG grinding wheels were carried out compared to rose-pink alumina (RA) grinding wheels. To clear the wear characteristics of the wheel working surface in creep feed grinding, changes in

The influence of grinding speed on the creep-feed grinding process

Journal of Mechanical and Energy Engineering, 2018
Grinding is usually the last stage of the technological process and determines the quality of manufactured products. One of the varieties of grinding more and more often used in practice is deep grinding which is called Creep-Feed Grinding. It is characterized by a high value of grinding infeed and slow feed.

Ultrasonic Assisted Creep Feed Grinding of Inconel 718 [PDF]

Procedia CIRP, 2013
AbstractThe paper details the effects of depth of cut and vibration amplitude when ultrasonic assisted (US) creep feed grinding Inconel 718 with an open structured alumina based wheel. The workpiece was actuated at a constant frequency (∼20.5kHz) via a block sonotrode attached to a 1kW piezoelectric transducer-generator system.

Creep-feed grinding of advanced ceramics.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1987
Advanced ceramics have some excellent properties which are suitable for mechanical components. It is, however, quite difficult to grind ceramics with high efficiency because of their high strength, hardness and brittleness. Now, creep-feed grinding is well known as an effective technology to increase the productivity of form grinding.

Thermal Analysis of Creep Feed Grinding

Procedia Engineering, 2015
AbstractCreep feed grinding is an abrasive finishing process characterized by low feed speeds (0.05-0.5 m/min) and very high depths of cut (0.1-30mm). Thanks to the extraordinary material removal rate provided together with a high shape accuracy obtained over complex profiles, this process has become the main competitor of milling.
