Dimensioning Sheet Metal Parts

Fabrication tolerances for dimensional variance in sheet metal and machined parts overview protocase takes great care to manufacture your electronic enclosures parts and components as accurately as possible.

Dimensioning sheet metal parts.

In dimensioning a single part its relation to mating parts must be taken into consideration. Fabrication tolerances for dimensional variance in sheet metal and machined parts. Intent of the sheet metal component. Uncontrolled dimensions on the other hand refer to the sections of the part where the bend originated from.

Following all sheet metal design guidelines is very difficult in the complex part. These mating dimensions should be given on the multiview drawings in the corresponding locations as shown in b and c. My boss dimensions from outside the flange walls and thinks. Those dimensions common to both parts are mating dimensions.

In this article we will discuss sheet metal design guidelines for manufacturing parts using sheet metal press bending. And also find you fold centers more easily. When designing parts for laser cutting one should not make holes smaller than the thickness of the material. But testing these exceptions before design release is a good practice.

Therefore exceptions can be there for complex features design. Your manufacturer may not be able to match dimensions when creating the actual sheet metal part due to tooling and equipment limitations. Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured. Bends in sheet metal are manufactured using sheet metal brakes.

When producing drawings of sheet metal components i dimension from inside the flange walls. A 1 degree tolerance on all bend angles. For instance in a a guide block fits into a slot in a base. Controlled dimension bend tolerances are standalone and therefore do not need to be considered in relation to any other bend.
