guy's i have attached the file which i used to program a cavity using 60 degree 0.1 tip tool , the
results and surface finish is pretty bad , can anyone help me to get smooth part
can anyone help me hoe to program the cavity
Hmmm, a few things going on here, one is that your second pocket is not clearing out all the material, either needs a smaller cutter or bigger Radii in those corners
Your feeds are too fast, need to slow down to get a better finish and make sure that you have a really good sharp tool, looks more like it is just "pushing" material out of the way rather than cutting it.
If you can get all the material properly cleared out of the pocket then one way to get better finish and get the sharp internal corners that are in your Model would be to use an "Engrave" toolpath at a single depth to do a single pass to clean the surface.
Have a look at the attached file, I have just added an "Engrave" toolpath that I think would be OK if the pocket is fully cleared out, as you can see in the image below the shape is cut cleanly but there are still the left over material from the pocket that is the problem with this method. Anyway, modified file is attached for you to look at as one example of how to finish it off.
