There are typically 3 terms used to represent a cycle time, and as we said before, defining those terms varies from manufacturer to manufacturer.ġ. The short answer is yes, but we’ll dive into more detail.

But, confusingly enough, that same term is also used to reference the entire process – from start to finish. Some machines produce multiple parts per cycle while others only produce one.Įssentially, cycle time is how long it takes to complete a job. (Don’t get Cycle Time confused with Takt Time, though, which is a pretty common mistake.)Ĭycle Time: This is how long it takes to make a part or how long it takes the machine to complete a cycle. Fortunately, it is easy to calculate and understand. It is also a critical part of the OEE calculation ( use our OEE calculator here). It is used by ERP and MES systems for scheduling, purchasing and production costing. The Cycle Time Formula is an essential manufacturing KPI to understand in manufacturing. “Flow is at the heart of the lean message that shortening the elapsed time from raw materials to finished goods (or services) will lead tot he best quality, lowest cost, and shortest delivery time.” However, accurately setting cycle time to monitor and measure the entire production process is key to success for manufacturers. Let alone the fact that it can be hard to calculate on the floor given all of the factors that contribute. Every manufacturer defines and measures it differently, adding to the confusing nature of applying cycle time from one company to another.

If you would like to learn how to reduce your PPM while increasing profits I can help.įirst by demonstrating a systematic and scientific approach to design and manufacturing in your facility. If you don't measure it you can not control it. It is the result of careful planning, design, and execution. Quality can not be inspected in after the fact. We can now control the process in order to control the quality. The monitoring and measurement systems we have today have paved the way for improved quality. Insanity is doing things the same way we've always done them and expecting different results. Impossible? Yes if you are still using the same manufacturing methods which were responsible for the 5 or 10% scrap you used to accept.Ī friend of mine had the following quotation on his wall: Way, one bad part per day! Notice I did not say one bad part per day per

That means that you would be allowed 25 pieces for everyġ,000,000 pieces or 250 defective parts per year. Let's assume your customers requirementsĪre 25 PPM. Like most companies, your plant operates around 5 days a week, 50 weeks Say, you produce 10,000,000 parts per year for your customer. To calculate: For example, let's say you had 25 pieces defective in a shipment of 1,000 pieces. Now the rate for most automotive components is targeted at 25 PPM or 0.0025% There was a time when you were considered a pretty good supplier when your defect rate was less than 1%, (10,000 PPM), then the expectation was increased to 0.1% or 1,000 PPM. PPM (Parts per million) is a measurement used today by many customers to measure quality performance.ĭefinition: One PPM means one (defect or event) in a million or 1/1,000,000
