How to model worm using parameters and relations with involute tooth profile

axial pitch of worm = 10 mm
lead of the worm = 10 mm (single start worm)
worm pitch dia = 33.5 mm
lead angle = 5.3717 degree
addendum = 3.15 mm
dedendum = 3.78 mm
tip circle diameter of worm = 39.8 mm
root circle diameter of worm = 25.94 mm
clearance = 0.63 mm
length of the worm = 46.145 mm
tooth thickness of the worm = 4.93 mm

if possible plz give me steps..

If you have solid works to hand I have two gear models with involuted profiles and parameters on my models...

Are you trying to model a completely accurate involute tooth profile? I have used SolidWorks with a add-in named GearTrax to accomplish this in the past. Please visit and reviiew the different add-in solutions for most of the popular cad programs. The GearTrax program is fantastic.

for involute tooth profile you will have to sketch an involute curve using the parametric equation of involute.
then do some trimming & sketching to get a profile in curve form.
you cannot extrude, etc it to create a solid body.
you will have to create quilts, trim them using the profile curve, then thicken or solidify them.
