In machining, "efficient" refers to the amount of material removed per revolution. The chip load is measured in Inches Per Revolution (IPR). A higher or lower IPR will increase production costs, as a lower IPR means less profit. A lower IPR means poorer cutting action, as the machine will not produce enough material in one cycle.
Usually, an acceptable efficiency rate in machining is around 90%. When a CNC machine can produce five-tool bits per minute, it should create 2,000 tool bits within 400 minutes. If a machine runs at 100 percent, the rate should be lower. The operator in charge of production slowed the production cycle, so it took 1.5 minutes to produce five-tool bits.
The operator in production stopped the CNC machine when the machine reached 2,000 tool bits in 400 minutes. It was not yet fully optimized, and the operator in charge of the machine slowed the production cycle. The next time he started a CNC machining project, he decided to slow the production cycle down. This allowed him to see if there were any areas where he could improve efficiency.
Generally, an optimal rate for CNC machining is around 75%. The machine should produce 2,000 tool bits in 400 minutes if it is running at full capacity. The operator in charge decided to reduce the production cycle, and it took 1.5 minutes to make five-tool bits. This shows that an average CNC machining machine is a more efficient option for a company.
In today's manufacturing environment, time is of the essence, and maximizing your time can save your business a lot of money. That's why they use multiaxis and 5-axis CNC machines that can help you maximize your efficiencies. You can use software designed for monitoring your machines and their output so that you can optimize your time and money and get the best out of your CNC machining operations.
A CNC machining machine should be able to produce five-tool bits per minute so that you can achieve the optimum production capacity. For example, if your machine can produce five-tool bits per minute, it should be able to produce 2,000 tool bits in 400 minutes. If you want to maximize your efficiency, a machine should produce 2000 tools in four hours. Nevertheless, a machine capable of producing a thousand tool parts will need to be more complex than a simple one.
A CNC machine that can produce five-tool bits per minute is considered efficient if it can produce 2,000 tool bits per hour. Ideally, a machine should produce up to two hundred tool bits per hour. If the machine can't reach this level, it's time to upgrade. But, what is an acceptable efficiency rate in CNC machining? High quality of work means that a machine will be profitable.
The higher the efficiency rate, the more value-added the production. For example, a CNC machine that can produce five-tool bits per minute should produce 2,000 tool bits in 400 minutes. At this rate, each machine should have the ability to produce a thousand tool bits per minute. The operator in charge must manually adjust the feed rate during its production cycle. This means reducing the feed and increasing the output.
Considering these two factors, an OEE calculation can be useful. The operator in charge of a CNC machine, for example, will be required to take a 30-minute lunch break and take a 40-minute oil break, which is the optimal production capacity for each CNC machine. In this case, the operator will switch off for 30 minutes. This leaves the machine running for the rest of its working time.
