We need some more options to control thread passes in the thread turning operation.
When choosing a reduced infeed I need to be able to specify something to control the depth of the first pass. Increasing the number of passes with the current method of factoring a reduced thread depth has very little effect first pass depth. In this instance, I was cutting 4tpi Acme which are about .135"-.140" deep threads. The first pass was approx .03" deep. I understand there are some tools that can handle this, but many single point tools in difficult materials can't, and as stated changing the number of passes has little effect.
