I asked where the setter stands during fixture changes and found our FR5 unloading drawing has no open door or gripper body either. It only shows the steel blank at its pickup point. I want one complete access review for the proposed tool path and the people who maintain and change the fixture.
Use a survey with the door open, the full tool and held blank through the unloading sequence, and the setter's actual changeover equipment. Ask the integrator and setter to review the same candidate layout; neither check can stand in for the other.
Survey is arranged and the toolmaker is supplying the complete assembly. The setter will bring the changeover trolley to the review. I have left the arm choice provisional until those checks are done.
