Even though contact “drag” scanning and noncontact laser scanning are prevalent in our industry, there are many manufacturers who still use kinematic touch trigger probes. Questions often come up regarding when a probe should be replaced. Is there a best practice for troubleshooting?
Of course,…

Like most industries, the manufacturing sector is transforming rapidly. Because of recent technological advances and globalization, U.S. manufacturing is facing intense international competition, increasing market volatility and complexity, a declining workforce, and a host of other challenges. Yet…
It can take anywhere from six weeks to six months to build a 2,800-square-foot, two-story house in the United States, mostly because human beings do all the work. Within the next five years, chances are that 3-D printing (also known by the less catchy but more inclusive term additive manufacturing…
