![]() ![]() Is there anyone using 3 or 4 axis lathe CAM and if so, what CAM? Does anyone know of more hobby style CAM system that may be applicable? None of the usual 'affordable' packages - AlibreCAM, RhinoCAM, etc, do more than 2 Axis lathe work.Īs this is definitely a hobby and the lathe won't be earning any money, $4000 for CAM is way over the top. Most of these start at around $4000/seat. Very little doing a C axis - just the usual culprits - EZcam, Mastercam, Visi, the various options in Solidworks, etc There is a LOT of CAM software doing 2D lathe work - X and Z axis only, threading, etc. The key to using all this hardware, is software that can generate the G code to feed a suitable controller. The mill can be set axially or radially WRT the lathe spindle( manualy.) The I have an ER16 600watt spindle in the tool gang, holding end mills, etc. The intention is to use it in 'motor' mode - fed a 270KHz pulse train it turns at 2700RPM as normal spindle drive and then as a Stepper/servo ( it is internally closed loop - with encoder etc) to create a C axis with 0.02deg resolution/0.008deg repeatability. The lathe has a spindle motor that is actually a high power high speed servo motor, driven by step and direction signals. Folk may have seen my posts on the CNC lathe I am trying to build - it progresses well, but the associated software is lagging somewhat. ![]()
