A: The answer to this question can often be one of opinion and/or personal preference. After all, a lot of money, time, and research have been poured into developing traditional and environmentally certified cleaning products to help stop the spread of disease and keep people in all types of facilities healthy.
Like the optical or laser equipment, the parts must be taken to the system.
Analog versions can be more prone to operator error. ... Here’s a handy table to help understand the pros and cons: The SEI created the first CMM designed for software organizations and published it in a book, The Capability Maturity Model: Guidelines for Improving the Software Process [SEI 1995]. Because of its ease-of-use, more employees can be trained to operate ATOS. Pros and Cons of Antimicrobial Surface Coatings. © Copyright 2020 ISSA. Also, even though CMMs come with reticulated heads, measuring at abstract angles or various depths is not always an option. A final thing to keep in mind is the high initial price of a CMM, as well as the maintenance costs.
Antimicrobial coatings are typically applied to counters, walls, door handles, and other high-touch areas; HVAC vents and mechanicals; and many other surfaces. CMM programming can frequently cause a bottleneck in production because of the amount of time it takes to complete.
If countertops, for instance, are coated with these materials, it means that powerful cleaning agents and disinfectants often used in health care facilities may no longer be necessary. Even paint manufacturers are applying them to their wall paint and primer products to inhibit the growth of pathogens in facilities. What I will present are my opinions, along with some … Two and three point contact measurement is readily available. While two point systems will more readily detect ovality, where this is not a major concern, three point digital systems are, in this quality technician’s opinion, the best all-around option.

A final note: If parts are relatively small and can be in contact with other materials, robotics is often used with air gage instruments.

Q: When inspecting diameters with tolerances of .0005 and below, are there any studies relating to the accuracy of different inspection methods, such as a coordinate measuring machine (CMM) versus a digital bore gage with setting ring combination? The U.S. Centers for Disease Control and Prevention (CDC) “has found no evidence to suggest [antimicrobial coatings] offer any enhanced protection from the spread of bacteria and germs and that proper cleaning and handwashing are the best ways to prevent infection.”, Because of this and concerns about the substances used in antimicrobial products, some health care organizations are having second thoughts about the use of these coatings.

They’re perhaps the ultimate 3D measuring devices in terms of their combination of overall flexibility, accuracy, and speed. They have the potential to meaningfully lower the environmental impact of cleaning in a medical setting, where scores of different chemicals are used for a variety of purposes.
Non-contact measurement systems such as optical and laser equipment are bulky, expensive and impractical. Reprinted with permission from Cleaning & Maintenance Management magazine. Sorry, your blog cannot share posts by email. When I am inspecting parts in which ovality could be an issue, if the parts are readily portable, I will check a percentage with a CMM to verify their roundness.
In addition to determining the efficacy of antimicrobials in surface coatings, let’s avoid another problem like we had with lead in paint.
This is not much good in a production environment. Further, the report says, this market is expected to continue to expand significantly in future years. A coordinate measuring machine (CMM) is used to measure the physical geometrical characteristics of an object.

As of late 2015, the American Coatings Association had not yet determined “what the formal policy will mean for those who manufacture coatings and paints,” according to an article published by Durability + Design.
Hence it is essential to take the help of a CMM Coordinating Machine to measure the micro parts. Factors such as the increasing number of hospital-acquired infection (HAI) cases…are encouraging greater use of antimicrobial-coated medical devices.”. Now considered a billion-dollar industry, antimicrobial coatings are designed to inhibit the growth of germs and bacteria on a variety of surfaces, and health care is the industry that shows the greatest growth and growing demand. The rings themselves can be verified with a CMM or sent out for certification traceable to national standards. However, for speed, accuracy, practicality, and price, a three point digital bore gage would be the way I would go to verify product with tight tolerances.
The Pros & Cons of CMM ... CMM—short for Capability Maturity Model—is a set of rigorous standards for software development that's based on five levels.
If proven true, this would help reduce the environmental impact of cleaning in medical facilities significantly. This is important when process control is vital.
