I need to smooth out the inner surface of the spline as shown below.
The current design that I have now, if I send out for fabrication, will result in non-smooth surface with many lines as in example for other sample of fabrication, like this.
I need to get rid off the lines and get a smooth surface. I have tried adding 4400 points along the spline but still the lines are still exist. Anyway i took me a lot of time to add the points, since the method I found to do it requires me to only add 100 points per time. So I have to repeat the steps, let say if to add 1000 points, i have to repeat the steps for 10 times!
Instead of that method, anybody knows how to make the surface smooth when machining? I can give u the polynomial of the spline..
Thanks for your kind help!
