I have been granted US Patent #5,665,412 Newton's "Third Law No Longer Limits Feed Rstes of the Machine Tools" I have been notified that this patent has been cited in 128 patents which have been issued since. It indicates that the industry is taking it seriously. But my patent is so basic that there is no way around it. I also presented a technical paper on it at IMTS 98.
In essence the patent covers a vertical machinig center that can start - stop heavy work piece instantly, without jerking the machine's frame. It does not depend on balancing or counter weights. The effects of Newtonian reaction forces from starting stopping the table are completely gone. The machine has no size limit, it has no catilevered ways or tables, it requiers less floor space, for machining the same size work piece as a conventional VMC, it's wear does not cause steadily increasing pitch, roll and yaw errors. And most important, the machine is more rigid and cost less to build than a conventional VMC for machining same size parts.
It is interesting to note that feed rates, especially for aluminium, are no longer limited by the cutting tools, but by practical limits of 'g' loads that starting and stopping of a heavy table imposes on the machine's frame. Use of linear motors does not solve that problem. But my invention does.
I have other patents which cover several variations of the same machine and patents for other metal working machines and instruments. I am interested in a joint venture to start building these new machines.
