I'm using add-in HSMWorks 2016 profesional running in Solidworks 2016 as well.
Are you happy with it? I have been having tons of weirdness going on in SWKS 014, going to try SWKS015 maybe today. I am holding off upgrading to SWKS016 till another service pack comes out.
We have HSMworks and have been testing more than 1.5 year with the turning module
in the hope it gets usable for us but we still do not use it in a production environment.
It has too many bugs and we consider it dangerous for the user and the CNC machine.
Only changing some cutting parameters can cause the worst crashes and even many simple
parts fail. The worst is that once you find a workaround and have some confidence only changing
a cutting parameter can crash your machine. I have sent many examples to our reseller but
they can't do much for us. We also don't get SPR numbers for cases where turning paths are
having bugs so it doesn't get the attention either.
We use Solidcam for milling and bought HSMworks for turning but that turns out to be a wrong decision.
