To most efficiently teach 2/3/4-axis turning centre and 3/4/5-axis machining centre programming / operation for the largest market the most popular programmings methods + widely used CNCs to prepare the most cost-effective turning and machining centres should be offered.
The most popular programming method is by using a CAM (Computer Aided Manufacturing) system such as the widely-used Mastercam and Autodesk Fusion software:
in combination with the world's most popular machine controls for 2/3/4-axis turning centres and 3/4-axis machining centres such as the Fanuc 0i-model F Plus series, the Fanuc 30i/31i/32i model B Plus series and the Mitsubishi M80/800 series:
which Masteel and many other suppliers offer on cost-effective turning and machining centres.
The world's most widely used controls for full 5-axis machining is the Heidenhain TNC7 series and the Siemens One series:
which Masteel and many other suppliers offer on cost-effective simultaneous multi-axis machining centres.
Another popular programming method in smaller shops is using fast conversational cycles for 2/3/4-axis turning and machining centre programs which are built in the CNC. For this the above Heidenhain + Siemens controls include full conversational programming cycles for simple 2/3/4-axis applications as do the following cost-effective Fagor 8065 / elite controls:
Conclusion: to best serve the largest machine shop market a combination of cost-effective turning / machining centres with the most popular non-machine-brand-specific CNCs (like all the above) should be used by its schools to best-prepare its students for fast integration - all without accepting any brand-subsidized conflict of interest.
Once a student has completed the above schooling and started programming and operating a turning and/or machining centre for an end user the student can easily adopt machine-brand specific controls on any machine brand-specific turning and/or machining centre.
