The initial attempt at Multi-Point machining was due to Warkentin, in which the tool orientation and position were optimized to reduce the gap between surface and tool at two points. The increased side-step results in reduced machining time. Thus, the side step in this case can be wider than the ribbon, usually a few millimeters in comparison to a 3-axis tool poistion in which the sidestep is a fraction of a millimeter.
Since the two contact points are spaced apart, the ribbon in-between and around these points meets surface finish criteria. Visting these the tool can cut the desired surface. Sliding the coin along a predefined path (tool path footprint) results in numerous tool position and orientations. Replacing the coin with a tool gives one tool position and orientation. It sits in the die touching it in two or more points. The coin is cylindrical with rounded edges, a torus in other words.

In this research it is proposed that these elemtent and some others are woven into a virtual machinist, a software observer, that can be the first step to autonomous machining. Given a part, a raw stock and a library of tools the virtual machinist should be able to machine the desired part. In addition, the simulator also trackes the movement of the tool relative to the raw stock, the forces experienced by the tool, the onset of chatter, the tool life etc. As the machine moves, so does the simulted machine etc. Virtual Machinist is a concept that knits the movement of th e machine with a simulator. Thus whenever a part is to be machined the machist has to be close to the machine. This makes the machinist a part of the system. The machine only follows commands, the final result depends on the machinist. Virtual Machinist: Computer Numerically Controlled (CNC) Machines follow a part program to move the tool as per the directions of the programmer. This agility can be used to position the cutting surfaces of the tool in close proximity to the desired surface. 5-Axis Tool Positioning: 5-axis Computer Numeric Controlled (CNC) machines are agile and can freely position and orient the tool axis.
