Sheet Metal Drawing Gd&T at Drawing

Sheet Metal Drawing Gd&T. Bottom bending and coining allow for a better control of the bending angle as springback is reduced. All drawings include gd&t and machining specifications and if required dimensions could be linear or ordinate depending on customer's request.

In most cases loosly fit hole dimensions are suffice. All drawings include gd&t and machining specifications and if required dimensions could be linear or ordinate depending on customer's request. It’s an elegant but not a simple system.

Close to 50% of the gd&t drawings coming across my desk use the system incorrectly in whole or in part. Bottom bending and coining allow for a better control of the bending angle as springback is reduced. Geometric dimensioning and tolerancing (gd&t) is a method of specifying geometry of physical objects on conventional or cad drawings, along with allowable variations (tolerances) in form, size and orientation. Gd&t contains an exact instruction how to measure and eases work for quality control or inspection.
