![]() ![]() The first two are not much of a problem because Autodesk HSM calculates very quickly and most modern controls have at least 1MB of RAM. It is tempting to always use very tight tolerances, but there are trade-offs including longer toolpath calculation times, large G-code files, and very short line moves. More lines result in a toolpath that more closely approximates the nominal shape of the spline or surface. How accurately the toolpath matches the desired shape depends largely on the number of lines used. To accommodate this, CAM approximates spline and surface toolpaths by linearizing them creating many short line segments to approximate the desired shape.
