We run very high volumes. Some jobs are 2 million per year through vertical machining centers. What is a typical defect per million in a machining environment?
Thanks,

A guy I knew who was a machinist but did not own his equipment. He rented time in a shop or had some type of arrangement with the owner. In a run of parts he would check the first, middle, and last part. That was it, he said it takes too much time to check every part. He did a few jobs for me before I started on my own. He was never between jobs, always busy.

Back in "six sigma" days the goal was 99.9997% good parts. Frankly, you're not going to achieve that off a machining operation short of spending zillions. Inserts break, material has defects, and so on. But it would be achievable on an outgoing quality basis -- you'd have to detect the various failure modes, eliminate what you could, and scrap those few bad parts before they reach the customer.
On edit: BigB's plant actually achieved that 99.9997% Probably a pretty good story there of tracking down failure modes; as well as scrapping (or reworking) a few parts (like the ones where an insert broke prematurely) before Toyota ever saw them.
Essentially, one American is responsible for changing the course of Japan's manufacturing: William Edwards Deming.
And this was after the Big 3 scoffed at him, even to the point of ridiculing his principles. . .
...... but it does seem that Ford and GM make better products today than before......
