The primary challenges come into play when dealing with geometric complexity, material mix, including titanium alloy components in high-end products, and shorter time-to-market cycles, all of which require increased accuracy and faster processing, not readily available in a lack of professional 5-axis machine knowledge.

This paper offers a detailed discussion on overcoming challenges with 5-axis CNC machining technology and will reference authoritative standards to ensure accuracy. The following discussion will go on to provide key points on advantages, materials that can be processed with 5-axis machines, and examples that can be learned from within 5-axis machining technology.

What Are the Basic Benefits of 5-Axis Machining in the Production of Consumer Electronics?

5. axis CNC machines offer basic benefits over traditional 3-axis machining, mainly because they offer a tremendous reduction in required setup times. Although they provide the flexibility to move the machine along five axes, they enable finished complex components to be accomplished within a single clamping, reducing the average number of required setups from five to one only. This process further reduces accumulated errors, resulting in enhanced overall dimensions, with a precision level of ±0.005mm. The need to manage such precision is emphasized by the fact that there are specifications such as ASME Y14.5, meant to cover the guidelines on dimensioning and tolerancing.

The efficiency improvements are significant, which may translate to the shortening of lead times by up to 30%. This assumes much importance in the fast-moving segments such as the smartphone industry, where the quick prototyping of aluminum housing for the likes of the iPhone may be achieved without having to incur the cost of changes.
