A micro-machining center, in the form of an automatic screw machine, utilizes an array of tools and machining support mechanisms removably mounted on a carriage movable parallel to a first axis, and a spindle/collet mechanism movable parallel to a second axis, with machining and manipulating operations being conducted at the intersection of the two axes in a common plane. A microprocessor control system having multiaxis command capability precisely drives the carriage and spindle/collet mechanisms separately or concurrently to perform a sequence of supported machining functions for fabrication of a given part from stock. With this arrangement of microprocessor, tools and spindle/collet mechanism commands for manufacture of a part can readily be generated, verified, used and retained in storage for later use. The system operation is greatly facilitated by a video display providing a magnified image of stock and tool positions and machining operations at the intersection of the two axes, together with a joystick control and single step operation through the sequence, made possible by the microprocessor system.
