Basics of Grinding - Manufacturing

2003-6-3grinding machines perform the dressing task automatically. The application of coolants to the grinding process is important. Coolants reduce grinding machine power requirements, maintain work quality, stabilize part dimensions, and insure longer wheel life. Coolants are either emulsions, synthetic lubricants or special grinding oils.

Identification and control of wet grinding processes ...

2016-12-22used to analyse the system and to design the suitable control strategy. As the KZC wet grinding process is a Multi-Input Multi-Output MIMO system, we propose a decentralized control scheme for its simplicity of implementation. To overcome all the control issues, a Double Internal Model Control DIMC scheme is proposed.
