Usaly engineers do this sort of thing for a resson and your find out why when you remove it ! . The setup and operation of work pieces can get stuck in a time warp just because it works and the engineer dosnt get paid anymore for altering the setup to make happen faster. Has the work piece changed much and has the tooling improved since it was first programed ? otherwise rip it out and find out !.
I remember telling my old boss that i could remove 15mins from a operation on some large 750mm cooling plates ( with new programing ) that took one and a half hours a piece .... his reply was F**** off ( his exact words ! ) and then two months later we had a production meeting where ask anyone for ideas on cutting job times !!!!
So i got stuck in the time warp
