I don't mind spending £2-300 on suitable tooling, but without going to full custom tooling, I'm drawing a complete blank. Tapping in the lathe as a second op is looking like the only option, but given the length of taps involved, it's something I'd rather avoid, especially since one part will be awkward to quickly mount as it'll be rectangular. Given the width of the thread form, I fully expect to need to do the thread in multiple passes to get the required thread width. I had been considering 10 or 12mm, but even going up to 14mm to get a bigger minor diameter/hole size has yielded no results for thread mills. Acme and Trap on the other hand are available from a couple different suppliers for reasonable prices, which leaves me the problem of machining the corresponding female thread. And that is where the problem starts.įinding square threaded rod is akin to finding a blood donating stone. I've got an idea for something I'd like to produce, and although I could use some standard metric threaded rod, I'd quite like to use something quicker/squarer. This does not affect part files saved from FeatureCAM 2016, 2017, or 2018 versions, but may.
In a future update of FeatureCAM 2019, the ability to load part files saved from a 32-bit version of FeatureCAM will be removed. Sending these extra files means we are more likely to reproduce your error and correct the problem.Has anybody came across examples of Square, Acme, or Trapezoidal threads being milled? 32-bit file compatibility: This release supports the loading of legacy 32-bit FeatureCAM part files (.fm.
