In atttached drawing sheet metal thickness is 0.8mm, when i do tolerance stack up analysis in worst case i am get interference of - 0.3 & clearance of 0.5mm.?
In attached drawing, sheet metal thickness is 0.8mm, when i do tolerance stack up analysis in worst case i am getting interference of - 0.3 & clearance of 0.5mm . I have a doubt why they have used +-0.2mm tolerance for hole position & overall dimension of the casing. If we do tolerance stack up analysis it wont assemble properly.
In many sheet metal drawing i have seen like this in worst case either it will interference occur or gap will occur if the tolerance is given +-0.5mm
So any one can help me in this tolerance value for sheet metal mating parts. How to consider the value of tolerance either based on the manufacturing or application.
