Structured light scanning is used to create a digital twin of a manufactured part, but we must understand the measurement reproducibility to best use the data.
Tool-toolholder-spindle-machine combinations each have a unique vibration response. We can measure the response by tap testing, but we can also model it.
Manufacturing and measurement are closely coupled. An important consideration for the use of measurement results is the associated measurement uncertainty. This article describes common metrology terms and provides an example uncertainty analysis.
The America’s Cutting Edge (ACE) program is addressing the current shortage in trained and available workers by offering no-cost online and in-person training opportunities in CNC machining and metrology.
Many cutter designs are available, and variable teeth spacing (or variable pitch) cutters can be used to influence milling stability. Let’s discuss why teeth spacing affects stability.
Tool-holder-spindle-machine combinations each have a unique dynamic response in the same way that each person has a unique fingerprint, which can be revealed using modal testing.
