Just adding my recent experience here. I'm not using any kind of tool wear compensation and didn't use it before because all the parts we do have a grinding finishing process after.
I'm using HSMworks + Solidworks with a modified version of a LinuxCNC post I found. I basically added a retraction in absolute coordinates before a tool change is requested and also the G43 code because it wasn't working. I'm also preventing the tool change process to take place directly in the tool component if that minimum safety distance is not met (a really important safety feature the mazak didn't have). I'm still getting along with HSMworks and some of its quirks but I'm pretty comfortable with it. I let the cam software handle all the tool geometry compensation and passes. Other safety features I implemented in HAL are: Avoid the opening of the chuck if the spindle speed is more than 1 rpm, avoid the tail spindle to be retracted if the program is in execution, and so on.. I attach a couple of videos of some parts I'm making. Please apologize the nasty turret but we machine mostly ductile cast iron (also I have a tiny leak since I changed the hydropneumatic clamping system to fully hydraulic despite having all new orings installed). And I know the program could be less shittier but you're seeing some of the solutions to the quirks of HSMworks. https://youtu.be/vSTmKIK1WtY https://youtu.be/v2lbs3fxO3A Leonardo Marsaglia El mar., 9 jun. 2020 20:16, Gene Heskett <[email protected]> escribió: > On Tuesday 09 June 2020 15:14:12 andrew beck wrote: > > > Thanks for the replies guys. > > > > Does anyone know how people cut tapered threads on their cnc lathe? > > > Depends on how much taper you need.
