Why a 3 Axis Mindset for 5 Axis Machining?

Sadly, all too often 5 axis machining is being done with a 3 axis mindset. It's one thing having modern 5 axis machines in the workshop but quite another to get the most from them.

This blog post explains why this conundrum is happening in many a workshop up and down the country and what to do about it.

CAD/CAM software and expertise

There are two things that need to be in place to get the most from the machines - software and expertise. 

Without an investment in software capable of creating the cutting programs to utilise a 5 axis machine's full capabilities, your engineering supplier will always struggle with complex projects. The machine may have the capability but, without the software, it will never be used!

Unless... the programmer isn't very good. 

When 5 axis machining has a 3 axis programming mind...

Without the experience and expertise to think through and plan the processing of a particularly complicated part, it doesn't matter what software you have. A 3 axis mind will always use a 5 axis machine like it's inferior 3 axis cousin!

Of course, if you are making small aluminium widgets, the 3 axis mindset will work just fine. Your 5 axis machine will get the job done in fewer operations, thereby saving time. So the programmer without the experience and expertise is adequate in this context.

Complex parts 5 axis machining.pngHowever, a motor racing wheel, an impeller or another complex part is a completely different story. Tricky work requires a 5 axis skill set built from years of experience. Years of figuring out complex programming to manufacture complicated parts.


It can be difficult to visualise a part machined with an upper turn, a lower turn, a main spindle and a sub-spindle all in the process at the same time. It is likely to be overwhelming for an inexperienced programmer. It certainly isn't for the faint-hearted!

Axis have been established for 30 years and, from the start of the project through to the end, everyone you speak to is an engineer with years of 5 axis machining experience and expertise. Your project will run smoothly, hand it over to us and have a hassle-free experience!

Your current supplier is satisfactory... or not!

Obviously, for complex projects to be successful the workshop must invest in the software to create the cutting programs that push their 5 axis machines to the limits. This combination of software and machinery provides the capability but, without the engineering experience and expertise, they might as well not have invested.

If you suspect their programmer of being inexperienced and using a 3 axis mindset for 5 axis machining work, it may be time to switch supplier. It's probably your only option...
