Hey there! As a supplier of Checking And CMM Fixtures, I often get asked about how to calculate the cost - effectiveness of these fixtures. In this blog, I'm gonna break it down for you in a simple way so you can make informed decisions when it comes to purchasing.
What Are Checking And CMM Fixtures?
First off, let's quickly go over what these fixtures are. Checking fixtures are used to verify the dimensions and tolerances of parts. They're super important in industries like automotive, where precision is key. You can check out more about Checking Fixture For Automotive Industry on our website.
CMM (Coordinate Measuring Machine) holding fixtures, on the other hand, are designed to hold parts in place during the measurement process using a CMM. These fixtures ensure accurate and repeatable measurements. If you want to know more about Checking Fixtures CMM Holding Fixtures And Gauges, just click the link.
Factors Affecting Cost - Effectiveness
1. Initial Cost
The first thing you'll notice is the upfront cost of the fixtures. This includes the price of the fixture itself, any customization, and shipping. As a Checking Fixture Manufacturer, we offer a range of fixtures at different price points. The cost can vary depending on the complexity of the part, the materials used, and the level of precision required.
For example, a simple checking fixture for a small plastic part might cost a few hundred dollars, while a complex CMM holding fixture for a large automotive component could cost thousands. It's important to get quotes from different suppliers and compare the features and quality offered at each price.
2. Lifespan
The lifespan of the fixture is another crucial factor. A well - made fixture can last for years, even with regular use. We use high - quality materials and advanced manufacturing techniques to ensure our fixtures have a long lifespan. If a fixture breaks down or wears out quickly, you'll have to replace it, which can add to the overall cost.
You need to consider the frequency of use and the environment in which the fixture will be used. For instance, if the fixture is used in a harsh industrial environment with a lot of vibration or temperature changes, it might have a shorter lifespan compared to one used in a controlled laboratory setting.
3. Maintenance and Repair Costs
Maintenance and repair are ongoing costs that you can't ignore. Regular maintenance, like cleaning, lubrication, and calibration, can extend the life of the fixture. However, if a fixture requires frequent repairs, it can eat into your budget.
We provide maintenance guidelines and support to our customers to help keep the costs down. For example, we might recommend a certain cleaning schedule or offer training on how to perform basic repairs.
4. Productivity Gains
One of the biggest benefits of using checking and CMM fixtures is the increase in productivity. These fixtures can speed up the inspection process, reduce the chances of human error, and improve the quality of the parts.
Let's say you have a manual inspection process that takes an hour to check a batch of parts. By using a checking fixture, you might be able to reduce that time to 15 minutes. This means you can inspect more parts in less time, which can lead to increased production and potentially higher profits.
5. Quality Control
Using high - quality fixtures can improve the accuracy of your measurements and ensure that your parts meet the required specifications. This can reduce the number of defective parts, which in turn can save you money on rework, scrap, and customer returns.
For example, if you're manufacturing automotive parts, a small error in measurement can lead to a part not fitting properly in the final assembly. This can result in costly recalls and damage to your reputation. By using reliable checking and CMM fixtures, you can catch these errors early and avoid these problems.
Calculating Cost - Effectiveness
Now that we've covered the factors, let's talk about how to calculate the cost - effectiveness. There are a few ways to do this, but one common method is to use the following formula:
Cost - Effectiveness = (Benefits / Costs)
Benefits
The benefits include productivity gains, quality control savings, and any other positive impacts on your business. To calculate the benefits, you need to estimate the time and money saved due to using the fixture.
For example, if you save 30 minutes per part inspection and your labor cost is $20 per hour, and you inspect 100 parts per day, the daily productivity gain is ($20 / 2) * 100 = $1000. Over a year (assuming 250 working days), the productivity gain is $1000 * 250 = $250,000.
If you also save on rework and scrap due to better quality control, you can add those savings to the benefits.
Costs
The costs include the initial cost, maintenance and repair costs, and any other expenses related to the fixture. Let's say the initial cost of the fixture is $10,000, and the annual maintenance and repair cost is $1000. The total cost over a year is $10,000 (assuming no additional costs for replacement) + $1000 = $11,000.
Cost - Effectiveness Ratio
Using the formula above, the cost - effectiveness ratio is ($250,000 / $11,000) ≈ 22.73. A higher ratio means the fixture is more cost - effective.
Making the Right Decision
When you're considering purchasing checking and CMM fixtures, it's important to look at the big picture. Don't just focus on the initial cost; consider all the factors we've discussed.
You should also think about your long - term needs. If your business is growing and you expect to increase production in the future, you might want to invest in a more expensive but more durable and versatile fixture.
