Introduction to Machining Milling MachineVertical Milling Machine is Most Common • Milling machines are very versatile They are usually used to machine flat surfaces but can also produce irregular surfaces They can also be used to drill bore cut gears and produce slots • The type of milling machine most commonly found in student shops is a vertical spindle machine with a swiveling head Although there are several other
MILLING CONTROL OPTIMISATIONSmooth operation of a milling circuit is difficult to achieve due to • The varying nature of the feed material size ore hardness etc • The unfavorable dynamics between feeders and the weightometer These dynamics degrade the performance of PID controllers making feed optimisation more challenging MillStar s Mill Feed Controller will • Compensate for the feed dynamics by
