Hello everyone, I hope someone on this forum can offer some advice. I asked this question on CNCZone Gcode programming but have not yet had a reply. Perhaps I didnt word it clearly enough so can anyone on this forum help?
I am in the process of building a cnc setup onto my wood lathe, to hopefully cut patterns onto bowls see (http://imagebin.org/45774). I am using emc to control the steppers. At the same time as this I am developing software to generate the gcode to cut the paths (see http://imagebin.org/45775), there may be many paths in a design. Paths probably will be wider than the milling tool used and deeper than the maximum allowable cut per pass. Therefore I am placing the code to cut a path inside a double loop. The outer loop will take care of the width and the inner loop will take care of cutting to depth. I suppose that I am cutting a long narrow pocket so cut full width to common depth then deepen or the other way round? Is one way better than the other so far as machining is concerned? Expanding this question to many paths - Is it considered better practice to cut all paths to the same common depth / width before looping to the next depth / width value, or is it better to cut each path individually to its finished width / depth before moving onto the next path. Or does it not matter at all. You will gather from my questions that I have no experience in milling (yet), this is a non-commercial retirement hobby project. I was an engineering apprentice 40+ years ago and did some then, but have spent the last 25+ years in computing. Hope that someone here will offer an opinion and I apologize in advance if you think this post is off topic.
