![]() ![]() I've copied the GEAR.LSP routine by DiamondJim from the 3rd page, but how is this LSP routine started once it's loaded into AuotCad? I get errors on the command line.Īlso read about using the formulas that Greg Gill had posted and that confirms what I've been attempting since starting this project to cut the internal spline on wire EDM. Questions that I have concern involute splines and I've read a few of the pages in the "Gears and Pulley Eng" forum. ![]() Ok, I think I know how to do this posting. ![]() RE: Drawing an involute spline onestout (Mechanical) 22 Jul 03 08:17 If its any use, i have access to AutoCad and Solidworks. Is the data i have provided sufficient to draw the spline? and if so can somebody please point me in the direction of the software (or some other way of drawing it.) I think i may need the major/minor diameters also - but i don't have access to very accurate measuring gear, so can i calculate the maj/min dimensions from the PCD/no of teeth? Ive got vernier callipers - can i just measure the outside diameter of the spline, or is it not that simple? And what about the "tooth thickness"? how can i determine that? (if its needed)Īny advice would be a big help! Somebody must have drawn splines before. I don't have any more data about the spline, but i do have the external spline on a shaft. I understand there is software available that can help with such a task? The spline in question is: Hi, i need a 2D drawing of an involute spline in order for me to be able to cut the internal spline using wire EDM. ![]()
