The US cutting-tools market: What changes lie ahead? | …
Cutting-tool companies could quantify this metric for each major metropolitan service area (MSA) in the United States to classify markets into three egories: small, medium, and large. For an even more insightful analysis, they could estimate the compound annual growth rate in machinery-manufacturing GDP for the next few years, again dividing it into three egories (low, medium, and high).
