Learn MoreManufacturing is a costly endeavor. Labor, raw materials, indirect overhead, and capital equipment are all large cost centers, and optimizing them is a goal of any manufacturing company. But one thing stands out among those costly line items. While all these areas have room for process improvement, machine utilization can make or break all the others.
The scary part: The average manufacturer has a utilization rate of just 28%!
With poor machine utilization, labor and overhead costs rise. It also impacts raw material in the form of inventory that doesn’t move as fast as it should. And in many cases, it can spur companies to purchase even more expensive equipment to keep up with demand.
Wouldn’t it be better to figure out how to make your machines run more effectively? Let’s explore how we can make that happen.
Machine utilization is a simple measure of the productivity of equipment.
The equipment utilization rate is calculated by dividing total run hours by the total number of available hours. Available hours constitute the number of hours the machine is scheduled to run and doesn’t include planned idle hours (such as weekends or nights).
Machine Utilization = (Run Hours / Available Hours) x 100
Also said as:
Machine Utilization = (Productive Machine Hours / Scheduled Machine Hours) x 100
Below are a few examples of how to calculate machine utilization rate.
If a machine in a single-shift CNC facility is scheduled to run eight hours a day, Monday through Friday, and due to setups, cleaning, breakdowns, and other operating tasks, only runs for a total of 30 hours, the utilization rate would be 75%.
30 Run Hours/40 Available Hours x 100 = 71% Machine Utilization
In another scenario, in a 24/7 facility, the equipment would be scheduled with no idle hours, and the total available hours would be 168. If the machine runs 85 hours, the machine utilization rate would be 51%.
85 Run Hours/168 Available Hours x 100 = 51% Machine utilization
Not only is every industry different, but every company within those industries is unique too. CNC machine shops making high volume parts for a consumer product with lower safety requirements will run with higher utilization than a CNC machine company making bespoke parts for aviation or making one part lots for complex, high-tolerance jobs.
The key to finding the optimum machine utilization is knowing the industry and application while having a firm grip on the standards and variables for each machine and part in-house. It’s also key to measure standards for lunch, breaks, fatigue, scrap rate, breakdowns, changeovers, and planned downtime.
But this requires companies to know these numbers and track them accurately. It also requires a data collection system that is free from errors and bias. This is the challenge faced by companies still tracking production data manually. If the data is unreliable or in error, machine utilization will be too.
That means you’ll be making decisions based on faulty assumptions.
Knowing your industry and market is only part of the solution. Today’s manufacturing environment moves fast and is hyper-competitive. Companies are turning to machine monitoring solutions to gain control of their data, put it to use in understanding machine utilization, and make improvements based on the insights derived from the data.
With MachineMetrics, a production monitoring platform, connecting equipment to get the data flowing is easy. The platform easily connects to any make or model of equipment, ensuring both digital and analog legacy assets are connected.
Most importantly, MachineMetrics standardizes the data into a common model. This ensures the data is ready for actionability, driving visibility with dashboards on the shop floor, pushing automated notifications, and running workflows to manage shop floor processes. For example, Wiscon Products, a precision parts manufacturer, was able to increase machine utilization by 30% using machine monitoring.
With accurate, real-time data in hand, a company can benchmark itself to understand the true performance of the operation. Many companies are stunned when the returned data shows them a significantly different picture than what they had assumed was their performance rate.
When using MachineMetrics to benchmark yourself, gaps in performance become immediately visible, and managers can begin to take action to improve equipment utilization. Real-time decision-making also becomes possible. Cycle time, breakdowns, scrap outs, and other information inform managers and operators of what steps to take to reduce downtime and increase run time.
MachineMetrics’ Utilization Report breaks down data even further to capture different visualizations of what is happening at the machine level:
All these views and more are unlocked when machine data is used to tell the story.
Analyzing machine utilization in MachineMetrics helps to not only identify your actual utilization but also pinpoint areas for improvement, such as process bottlenecks and downtime reasons.
With control over data and actionable insights that reduce downtime and improve decision-making, many advantages come with higher machine utilization. These include:
MachineMetrics is fully automated and lets you visualize real-time production data on your shop floor. Be notified instantly of problems and use historical analysis and newly revealed trends to improve uptime and create great machine utilization.
Leverage equipment utilization reports to to spot issues at the operator, machine, cell, or plant level and drill in to understand what's causing the problem. With an accurate, real-time measure of shop floor performance, you can easily spot opportunities to increase OEE.
