thanks for the help people got this cracked now, parts from another manufacturer arrived and fit perfect, just had them inspected and there within 0.01mm of my 1st off!
converted the circular tooth thickness to radians then into degrees and it makes sense doing it this way, ive just finished an internal and external of the same size, i ran the wire with a standard offset of 0.175 (0.3 wire plus spark gap) the od and id measure bang on size and im gonna keep the...
at 1st i was just going 360 divided by teeth and geting 7.5, but realising that this would cause interferance between internal and external i realised that the tooth thickness had to goveren the width and the only way i could draw it was to convert the circular tooth thickness into an angle so i...
I need to be certain im drawing these things correctly, if im wiring these yes ill be using compensation i.e G41-G42 on my wires, and yes i can just alter the wire comp size till it fits but checking these things is going to be difficult and chances are ill be using the OD ind ID to check its...
im going to clarify my last comment -
i have the drawings for mating splines and on the external spline the circular tooth thickness is given as max effective = 0.0982 and min actual = 0.0953.
then on the internal spline its givin as max actual = 0.1011 and min effective = 0.0982.
what size do...
rite i think ive nearlly got it! - since dinji pointed out im stupid i went on some maths site and sussed the maths out, i can get circular tooth thickness into degrees, wahoo.
so only 1 question left - what size do i use for circular tooth thickness, is it in the middle of max effective and min...

i opened your file and its identical to my 1st attempt, if i draw an internal and external the same they dont fit together, yours measures the same as mine? and i think the tooth thickness needs to be reduced. it measures 0.098 linear??????
thanks for the reply's everyone!
i only have one problem now, when i draw and internal and external side fit spline then place them on top of each other there is clearance on the minor and major but the splines are touching, no clearance, the circular tooth thickness on both drawings is...
CAN ANYONE TELL ME SOFTWARE I CAN USE TO DRAW UP AN INVOLUTE SPLINE I HAVE ALPHACAM BUT IT ONLY DRAWS AN INVOLUTE CURVE, AND IVE TRIED LOADS OF WAYS BUT ALL THE SIZES DONT MATCH AND IM STILL UNCERTAIN IF IT WOULD MATCH THE MATING PART AND HAVE NO WAY OF CHECKING AGAINST IT.
THANKS FOR THE REPLY
can anyone help me please, im having trouble using this site as ive seen this question answered on here but cant comment on it! - im wondering if anyone can translate my info into a dxf file please?
