5 axis machining is becoming more commonplace in modern CNC shops, and unlike the belief of many, it is not as complex as it may seem. Below are some of the basic of 5 axes CNC machining, and a look at the benefits it has over traditional 3 axis setups.
What is 5 Axis Machining?
A CNC machine that works on 5 axes is an advanced CNC machine. Unlike a traditional 3 axis machine that is only capable of moving in the two directions of X and Y and up and down on the Z axis, a machine with 5 axes can move a part or tool on five different axes simultaneously. 3 two extra axes that are used with 5 axis CNC machining are A and B, these two axes being rotary axes which allow the cutting tool to approach the part being worked on from all possible direction.
Is Machining on 5 Axes Complicated?
There is a general misconception that machining on 5 axes is complex and time consuming as well as expensive, requiring the most up to date and costly CAD and CAM packages. This is partially true as you will need to invest in a system that is capable of working on 5 axes. There are indeed only a handful of controls that we enable you to program a machine for 5 sided machining without a CAM system in place. Making the transition with existing machinery and the introduction of new software is rarer still, meaning that you will need to invest in some very worthwhile new equipment and software if you wish to mill or turn on 5 axes.
Should I Invest in 5 Axis Machinery and Software?
A few decades ago, the smaller CNC shops around the UK were poised with the question of whether they should switch from manual machining to CNC, aware of the initial cost. The question nowadays is whether to switch from 3 to 5 axes, and the answer really is yes. People who failed to follow suit and drop manual machining have been left behind. In order to stay on top and offer a service or product that is as good as or better than those of your competitors, you do need to continually invest in new machinery.
All machining shops will benefit from 5 axis X CNC machines, allowing them to make parts that are more complex and to a higher grade of precision than those that are manufactured using 3 axes. Ignoring advances in CNC and CAM technology will only result in you getting left behind and eventually losing faithful customers to competitors who are willing to make the investment. A sensible way to slowly introduce 5 axes machinery to your own shop would be to gradually replace machines. Instead of paying out for parts to be replaced on existing machinery, invest in newer and better machinery that will serve you well for many decades to come. Building up your CNC shop in line with your competitors is crucial for your success. No one likes to get left behind.
