Control for the Mill 201

The class "Control for the Mill" provides an overview of the Okuma OSP-P300 control for the mill. The class covers the two main parts of any Okuma control, the NC panel and the machine operations panel, and describes each of the key groups contained within these panels as well as the function of each individual key. In addition, "Control for the Mill" touches on the advanced software operations possible with Okuma's open-architecture design philosophy and Windows-based control.

Knowing how to quickly and easily operate the OSP-P300 control is necessary for the operator of any Okuma machine. Gaining a deep and thorough understanding of the control allows operators to take full advantage of the OSP-P300's functionality, resulting in quick production runs and precise finished workpieces.
