Jan 23, 2013 First, an experiment was conducted in a CNC cylindrical grinding machine. The TM using L 27 orthogonal array was applied to the design of the experiment. The three input parameters were workpiece revolution, feed rate and depth of cut; the outputs were vibrations and surface roughness.
Dec 01, 2003 Tim Hykes, manager of controls engineering for Landis Gardner, agrees, noting that the company’s latest 6400 CNC control is already able to handle the input from sensors monitoring the grinding process as well as data from the servomotors on the machine—capabilities that will be addressed as part of the intelligent grinding R&D activities.
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 …
The importance of the plunge grinding system parameter, i.e., the time constant, is discussed and the system for the grinding process is described. An in-process time constant estimation method that involves only a few mathematical operations is presented. The method is particularly useful for adaptive control of the plunge grinding process.
The main parameter influencing particle size from the circuit is ore feed rate. Although other factors like water addition, grinding media loading, etc. play a minor role, it was assumed that these in-circuit parameters remain constant for purposes of the control strategy. Water addition at Cyclone 1 is used to control particle size
Sep 13, 2013 parameters are listed in Figure 5. Roll Grinding Procedures Successful roll grinding depends on many factors. The knowledge and experience of an operator, the condition of the roll grinding equipment, and continued preventive maintenance of equipment, all contribute to the ability to meet tolerances and finish requirements.
An example of the process control trend at Meadowbank is included in Figure , which shows the 6 ... 200 mesh.
