Marc Jenni, the way of his new in-house movement. Pt5, Pt6 & Pt7

Marc Jenni: Notes like these help me programming the CNC machine- each circle, arch, bow or hole needs to get referenced with its own position and depth.

Marc Jenni: When finally the CNC program is written, the fun may begin. You can spot the cut-out circles for the wheel train. View on my vintage Olivetti computer from 1995 with a CAM program running on Windows 3.1.

Marc Jenni: And back to the brass plate where the 0-position for the Z axis needs to be determined. (Check out the two little circles on the upper level of the plate). This process happens every time a milling cutter or a drill needs to be changed.

Kind regards.
