"It doesn't take a lot of time to gather this data either," Taylor said.
In this operation, three surfaces in four different locations are measured for a total of 12 data points.

"We had a vision of what we wanted to present to the operator on the shop floor," Taylor said.
"We wanted to give the operator more than data.
We wanted to give him a tool he could easily use to consistently produce quality parts.
By programming in the CMM lab, highly sophisticated measurement routines can be developed using the system software.
"Data reporting can be modified too," he said.
"Right now, we're concentrating on Cp and Cpk with capability charts, but we can have distribution statistics, a cumulative probability chart and other reports for quality assurance documentation if we desire," Taylor said.
