MINIMUM FLANGE WIDTH

The material thickness and bend radius

are used to determine the minimum

flange width that can be formed on a

power brake.

When a shorter flange is mandatory,

it can be made longer and cut to size

after bending.

DISTANCE BETWEEN BENDS

The minimum distance between bends can

be determined by adding the minimum

flange width to the bend radii plus thematerial thickness.

Simplified Chart of Clearance Holes for Coordinate

or True Position Dimensioning

1. Floating Fastener - Use the floating

fastener column when calculating clearance

hole dimsnsions for parts that are joined

by a loose piece, such as a screw or a rivet. However, if the screw, rivet, etc. is

flat headed and the hole in which the head

fits is counter-sunk, then use the fixed

fastener column. Any feature of the design

that fixes the position of the fastener with

respect to one of the mating parts will

put it in the fixed fastener category.

2. Fixed Fastener - Use the Fixed

Fastener Column when calculating clearance

hole dimensions for parts that are joined

by a piece that is held in a fixed position

by one of the mating parts. Examples of

this are studs, dowel pins, flathead screws

and rivets, fixed keys etc.

3. Diameters shown are based on true

position tolerancing formulas whereF = max dia. of fastener

H = minimum dia. of clearance hole and

T = positional tolerance dia., and then

the next largest preferred drill size waschosen.

For floating fastener: H = F + T and T = H - F

For fixed fastener: H = F + 2T and

T = H - F

4. This chart to be used as a guide only.

Diameters may change according to design

requirements.
