4.2 Process – What does the machine do?

The first step is about understanding the process. The process describes the logical sequence of the machine – independent of technology or hardware.

Example: "A workpiece is loaded, clamped, machined and removed."

Each of these sentences is already a potential state in the control logic:

• Load part → State 1

• Clamp → State 2

• Machine → State 3

• Unclamp → State 4

• Remove → State 5

The result of this step is a logical sequence of states – the basis for the control logic.

So each SEQ begins with the question: "Which states does my process need?"
