Universal Testing Machine (UTM for short), also known as universal testing machine, material testing machine or material testing rack, is used to test the tensile strength and compressive strength of materials. The early name of the tensile testing machine was the tensiometer. The "general purpose"

Research shows that the development of modern 3-axis machines began in the early 1960s and is a direct descendant of the modern 2-axis metrology machines invented in the 50s in various military defense industries.The first 2-axis universal measuring machine is believed to have been developed by the

CMM is one of the most effective ways to measure and obtain dimensional data, because it can replace a variety of surface measurement tools and expensive combination gauges, and reduce the time required for complex measurement tasks from hours to minutes, greatly Improve measurement efficiency.

The work plane was not noticed. Especially when the programming hand picks the coordinates for the initial construction, if the working plane is not switched to the straight line used to build the coordinate system, it is likely to cause the rotation direction to deviate greatly or be invalid, and almost all such programs cannot run or collide.
