Numeric ID 17621
Value Type PMString

DIN 5480 Part 1 defines the following manufacturing processes for spline connections:

Broaching

Addendum of basic rack profile hap 0,45 x mN
Dedendum of basic rack profile hfP 0,55 x mN
Root fillet radius of basic rack profile ρfP 0,16 x mN

A hobbing tool with this data is used for splined shafts.

Hobbing

Addendum of basic rack profile hap 0,45 x mN
Dedendum of basic rack profile hfP 0,60 x mN
Root fillet radius of basic rack profile ρfP 0,16 x mN
Mill broaching
Addendum of basic rack profile hap 0,45 x mN
Dedendum of basic rack profile hfP 0,65 x mN
Root fillet radius of basic rack profile ρfP 0,16 x mN

Cold rollling

Addendum of basic rack profile hap 0,45 x mN
Dedendum of basic rack profile hfP 0,84 x mN
Root fillet radius of basic rack profile ρfP 0,54 x mN

Different basic rack profiles can be used by specifying user-defined tools. This is also required if a diameter-centered connection is to be calculated.
