Not listing, straight up: right?
While surfing the apt stuff this morning I found a program called
cone.apt.
I looked appropriate to GH's problem. Edited version is listed below.
For some reason the loop limit doesn't kick in so it goes on past the
desired depth. Other than that it appears to work at least under sim.
partno cone from spiral
$$ This program profiles a cone by spiralling around
$$ the surface. It uses a parametric equation for a
$$ helix, and decreases the spiral's radius as it
$$ generates the spiral.

$$machin/pmill
cutter/0.125, .0625 $$ 1/8" ball nose
d1=4 $$included angle of cone
d2=.75 $$start dia
d3=.52 $$end dia
d4=.0i $$spiral feed per rev
d5=5 $$degree increments
endz=(d2-d3)/2/tanf(d1/2)$$depth of cone
goto/0,0,0
theta=0
tanAng=tanf(d1/2)

agn) z=-(d4/360)*theta
x=(d2/2+z*tanAng)*cosf(theta)
y=(d2/2+z*tanAng)*sinf(theta)
goto/x,y,z
theta=theta+d5
if(endz+z)quit,quit,agn,quit)

fini
It does need a few edits to work, etc Fn, G5n, M2 | M30 and truncating
the code at the desired depth.
