Hi all,
Recently, I started as a CAD engineer in a sheetmetal fabrication company. In my first week, a QC manager came and asked me to go over future drawings carefully for one particular company. He said if necessary, better to say we can't do it to the company. As they used GD&T specifications for all their sheet metal parts. And some of the tolerances/ spec. is quite high, which resulteed some parts were rejected. To tell a long story short, they tried to make fabricated sheet metal parts & bolt it together to construct a frame assembly (which another precision machinery sit on the top of it). However, due to imperfection of bending of flanges and hole locations positioning, the assembly was off.
I understand this is a challange to our shop as some of the parts will not work, if straightly go by the spec., but on the other hand, I am questioning if there is a straight yes/ no answer to this question. As I saw there are similar parts made some time ago (on the drawing database). Being a new guy, I don't want to reject the potential purchase order right away, as the management will get mad on me.
My department has a production manager (he basically in charge of everything technical under the roof, he is pretty busy), and a project manager (he is more focused on administrative tasks and schedules).
Any thoughts on this? Any advices help.
