Modern grinding processes are applied to a wide range of materials and
products from the very large to the very small. As exciting new products
are developed, the challenge of producing parts is often best met by a
grinding process using grinding wheels and controlled grinding machine
motions. This chapter seeks to introduce trends that have developed in
response to the challenges of higher removal rates and higher precision.
These trends include developments in abrasives, wheels, wheel prepara￾tion techniques, coolants, machines and process control.
