Beyond Purchase Price: Understanding Automation in Manufacturing
UK manufacturers need to get realistic about return on investment if they’re going to improve their automation levels, says Oliver Selby of FANUC. Despite our relative reluctance to automate, the UK recently overtook France to become the eighth largest manufacturing nation. If we are to continue competing on the global stage, however, then it is imperative that we increase our level of industrial automation – we currently languish in 25th position in the IFR global robot league table – not least because of the ongoing labour shortages across all areas of manufacturing. We are the only G7 nation to sit outside the top 10 robot adopters; that alone should inspire us to increase our levels of automation in manufacturing in order to drive higher productivity, greater efficiency, and increased output.
The True Value of Automation: Total Cost of Ownership
To do that, we need to get realistic about return on investment. Focusing on a sub-two year payback can lead to businesses making compromises when developing their manufacturing strategy, and thereafter their capital equipment and automation purchasing strategy, and forces decisions to be made that do not offer long-term value. By contrast, determining the value of automation in manufacturing using total cost of ownership (TCO) is a far more accurate measure. Any investment in capital or automation equipment should form part of a business’ long-term strategy, and not simply because the purchase price fits into an arbitrary short-term payback period. By calculating the lifetime costs – and more importantly, the lifetime savings – associated with automation, manufacturers can ensure that the sums add up in the long term and not just at the point of purchase, resulting in the right solution for their business both now and in the future.
Below are the nine factors that make up TCO lifetime costs. Before considering any automation purchase, make sure to talk to your supplier about how their solution can help to control these costs, to ensure you’re getting real value from your investment:
1. Purchase Price– While much of the focus of any negotiation is concerned with purchase price, it actually only accounts for between 15-25% of the total cost of ownership. Solely focusing on this as the deal-breaker can lead manufacturers to invest in an automation solution which may not be fit for purpose. While FANUC strives to make our products extremely cost competitive when it comes to the initial purchase price, with as much as 85% of the ‘hidden’ costs of ownership coming via other factors, it is counterintuitive for manufacturers to base their sole automation investment decision on this point.
2. Training – Whether your workforce is used to dealing with smart, connected automated solutions or is unfamiliar with modern robotics, some element of training will be required to ensure the full value of your equipment can be realised. We offer an array of upskilling resources from our dedicated training facility in Coventry, from basic operating courses to full programming and maintenance courses. Ensure your business can keep up with the pace of change in today’s digital world by making sure any automation supplier you choose offers full training for the lifetime of your purchase. It’s also important to focus on multiple stakeholder levels in the business. When adopting automation, different stakeholders will require different levels of understanding. For example, at shop floor level a technical level of comprehension will be needed; meanwhile, the C-Suite will need to understand the business case for automation.
3. Maintenance – Keeping your equipment running at optimal levels will ensure it delivers day after day, week after week, year after year. Our products are extremely reliable, so much of what we offer from a servicing perspective falls under preventative maintenance. We work with our customers to schedule any required maintenance at a time that’s least disruptive to their business, maximising equipment uptime.
4. Repair– The longer a machine is out of action, the greater the financial impact on your business. Speak to your supplier to find out what their average engineer response times are. At FANUC UK, we’re currently sitting at a sub-20 hour mean time to repair any faults, i.e., less than one business day.
5. Downtime– Preventing downtime to minimise production losses is essential. As well as ensuring your automation supplier offers preventative maintenance and short repair times, the best way to keep downtime to a minimum is to invest in equipment which has a reputation for reliability. Ask your automation supplier for evidence of its products’ mean time between failure (MTBF). For example, the MTBF for our CNC range is 25 years, and for our robots it’s even longer, at 32 years. Make sure you also find out from your automation supplier what services are available to support reduced downtime occurrences, such as augmented reality 24-hour support helplines.
6. Upgrades – With technology evolving at a rapid rate, your automation supplier should be able to equip your purchase with the latest smart software upgrades as they are released. At FANUC, these include our Zero Downtime (ZDT) programme, which tracks our machines when operational and feeds back performance data to ourselves and the customer.
7. Security– Hand in hand with technological advancements comes cybersecurity. Ensuring that your equipment, as well as the data it handles and produces, are kept secure is a prerequisite and something that we take extremely seriously. Make sure your automation supplier can clearly explain their cybersecurity measures to help your business avoid a costly cyber breach.
8. Energy– No longer a ‘nice to have’, sustainability is now a business imperative from a financial, environmental, social and governance (ESG), and legislative perspective; not to mention essential for winning and retaining key contracts. As well as questioning the energy efficiency of any automation solution in terms of the electricity and gas it consumes, make sure to also find out its credentials regarding water usage, particularly when it comes to keeping the equipment clean. However, some solutions go even further and actually re-use energy within the process. For example, our all-electric ROBSHOT injection moulding machine has an advanced power regeneration feature that enables intelligent energy recovery, meaning it consumes 10-15% less energy than other all-electric machines.
9. End of Life– Everything has a cost to recycle, so you’ll also need to factor in a plan for when your product reaches the end of its life. Of course, this will be determined by its expected lifespan. Will you need to recycle it and purchase a replacement in five years’ time or in 10, 15 or 20 years’ time?
