OEE in long-run milling process

Q: We are tool & die maker for  the automotive industry. Overall each die will take 20 to 35 days (based on size) to complete. Depending on the shape (contour) of the die, the process is done manually or auto mode. The mode depend on our CAD/CAM capability to do the programming.

How do we calculate OEE in this situation?


We have no information about maximum speed…

Q: Our textile printing machine runs different products (fabric type along with number of printing colors). We don’t have any information regarding maximum speed against each type of product (fabric type, number of colors etc.).

How can I calculate maximum (Theoretical) speed of my machine when no manufacturer data is available?
