We have a project to improve the yield of a drilling process on an older CNC machining center and I'm looking for some knowledge sources of current best practices on drilling 316SS.
Our biggest defect is a .1874+/-.0004 ID hole that sometimes ends up oversized. The drilling steps for these holes are: center drill, mill, turbo drill, ream. We use a recycled (filtered) Moly-D cutting oil that has been drawn from another CNC machine used for tapping. The oil is not pressure fed.
We have made these parts for years and have considerable experience at it, but haven't paid much attention to advancements outside our company.
So, what are my questions?
I would like to know some good sources of knowledge of drilling 316 stainless (i.e. vendor catalogs, associations, handbooks, etc.)?
Also, I want to test the validity of using recycled oil that is uncontrolled, but our "experts" believe to be more than adequate for the application. How can we test cutting oil? What are the best practices in PM of oils?
If anyone can give me some guidance or advice I would be grateful. Thanks.
