Let's look at this from an operator's standpoint and the burden it creates...
In an environment where one operator has to run several machines this creates an overload of unnecessary added stress for them to deal with. On top of their normal duties, (i.e. tool load alarms...tool life count alarms...insert changes...tool offsets...measuring...production...) they are now tasked with interacting with pieces of equipment that simply do not function as intended. When you get erroneous tool load or break alarms that occur randomly, in some cases back to back to back to back, it simply makes it more difficult for them to do their jobs and function as needed. They stress over getting pulled from functioning machines to attend to issues that should not be there. At some point you have the "little boy that cried wolf" syndrome hit and you start taking them less seriously. That can be catastrophic. The loss of production combined with the nuisance of recovering and restarting the machine(s) should make this a #1 priority for any machine manufacturer to resolve. Let's face it...Doosan is selling these machines with these options so shouldn't they function as intended??? We all know that load monitoring on any manufacturer's machine can have it's flaws but these issues seem to be ongoing for far too long. If load monitoring alarms repeatedly occur in air with no tool contact, why offer load monitoring??? And for the response from several techs to be "nobody else uses load monitoring" just seems a bit far fetched to me. In a production environment we simply cannot have this added downtime to any machine on any shift... especially brand new equipment. That's my two cents...
