I've tried but I can not fix it, it's like artcam want to create a circle from straight lines, please help
I don't use ArtCAM pro, but have made 3D displaying software.
I assume you are talking about what you are seeing on the screen. Not what you see in the G Code generated.
"it's like artcam want to create a circle from straight lines" you are correct!
Programs will draw circles on the screen using line approximations.
This is because calculating every point for a circle would slow the PC down too much.
One of my programs will draw circles using about 240 line segments, if you zoom in enough you might start to see lines (depending on how far you can zoom).
Stacking lots of circles on top of each other creating a cylinder wall you can start to see strange patterns.
Especially if the wall is one pixel thick, lighting calculations start to let light through at different angles. hence the sawtooth pattern.
So you shouldn't worry. You should think of the screen view as a good approximation of what you are doing.
G-Code results is what matters.
I doubt you will see any sawtooth in your G-Code results.
You can look at your G-Code and see circles (G02 and G03). And at every cut/pass depth you should see the exact same circle parameters.
Example C# circle calculation code using old OpenGL:
internal static void DrawCircle(ref OpenGL gl, float cx, float cy, float r, int num_segments)
{
gl.Begin(OpenGL.GL_LINE_LOOP);
for (int i = 0; i < num_segments; i++)
{
float theta = 2.0f * 3.1415926f * (float)(i) / (float)(num_segments);//get the current angle
float x = r * (float)(Math.Cos(theta));//calculate the x component
float y = r * (float)(Math.Sin(theta));//calculate the y component
gl.Vertex(x + cx, y + cy);
}
gl.End();
}
AORD thanks for your answer, I am a newbie in artcam
