Re: Spiral circle
hi, declare a step radial step, like 10mm for example : thus, the radius goes like this :
angle radius
0 0
90 2.5
180 5
270 7.5
360 10
360+0 10+0
360+90 10+2.5
360+180 10+5
360+270 10+7.5
360+360 10+10
actual_radius = step * ( how_many_full_circles + actual_angle / 360 )
... 0 <= actual_angle <= 360*
create a code & loop it; discretization is a bit tricky, because it is not direct proportional with the angle, but more with the radius ( i have to do the math to check this dependency )
using a variable parameter to achieve a constant discretization is another thing, that may be hard to implement within a cnc soubroutine; i can develop this if you wish / that's all
