In many machine shops, CNC capacity is seen as a fixed limit – prompting investment in new machines or longer hours when demand rises. But a growing number of UK manufacturers are taking a different approach, rethinking which parts truly need machining and shifting suitable work to faster, more cost-effective technologies like additive manufacturing<\/a><\/span> and 3D scanning<\/a>.<\/span><\/p>\n When lead times stretch or production backs up, the instinct is to add more resource. But in many cases, the issue isn’t a lack of CNC machines – it’s how they’re being used.<\/p>\n Across manufacturing, high-value machining centres are often tied up producing:<\/p>\n These are essential items – but they don’t always require subtractive manufacturing. The result is valuable spindle time being consumed by work that could be produced faster and more efficiently elsewhere.<\/p>\n If you’re currently machining any of the following, there’s a strong chance you’re limiting your own capacity:<\/p>\n CNC machining remains critical where it adds the most value:<\/p>\n Additive manufacturing offers a practical alternative<\/a><\/span> for many of the parts currently occupying CNC machines.<\/p>\n Instead of machining from aluminium, fixtures can be 3D printed<\/a><\/span> with optimised geometries, reduced weight, and integrated features. Lead times can drop from weeks to days, while improving ergonomics on the shop floor.<\/p>\n Design iterations can be produced quickly and cost-effectively, enabling faster development cycles without tying up machining resource. Companies can also trial this approach with minimal commitment by sending a part to the StrongParts bureau<\/a><\/span>, allowing them to evaluate quality, turnaround times, and suitability for their application before investing in in-house capability.<\/p>\n Additive removes many of the constraints associated with complex geometries, producing parts in a single build without multiple setups or tooling.<\/p>\n For forming or composite applications, high-strength composite materials, such as those used in the Markforged X7, FX10<\/a><\/span> or FX20<\/a><\/span>, offer sufficient durability without the time and cost of machining metal tools.<\/p>\n A common barrier to moving work away from CNC is the lack of usable CAD data<\/a><\/span>, particularly for older or obsolete components.<\/p>\n This is where modern 3D scanning plays a key role. Using systems such as the Artec Leo<\/a><\/span> or Artec Spider II<\/a>,<\/span> manufacturers can quickly digitise physical parts with high accuracy. The result is a faster, more flexible workflow that removes dependency on legacy drawings or time-intensive manual measurement.<\/p>\n Consider a typical scenario:<\/p>\n A production team is machining aluminium fixtures with a lead time of 2-3 weeks. Each design change requires reprogramming and re-machining, tying up CNC capacity and delaying production.<\/p>\n By switching to an additive workflow:<\/p>\n Lead time drops to days, iteration becomes simple, and CNC machines are freed up for higher-value work.<\/p>\n Reallocating even a small percentage of CNC workload can have a measurable impact:<\/p>\n If you’re unsure what could be moved off your CNC machines, we can help assess your current workflow and identify immediate opportunities.<\/p>\n >> Get in touch<\/span><\/a> if you’d like us to help.
