Inspecting bar stock for machining
Inspecting bar stock for machining
(OP)
My company will begin machining throttle shafts in-house and so we will need to inspect the bar stock as it arrives. We're using SUS 303 and 430F, maybe 12ft lengths. Does anyone have any thoughts on what to inspect the material for? I was thinkning straightness, verifying material certs, maybe some tensile testing...any ideas?





RE: Inspecting bar stock for machining
You can have many aspects of the bar inspected, depending upon the safety and functional requirements of the end product. More requirements may mean more raw material cost. You may want to consult with a materials engineer to help write a purchase spec. Even then if it is a safety part you may need to verify a few things. Hopefully this is a start.

Once you have a material specification, you can arrange to have periodic tests performed to sample the various heat of material that you receive at your facility. Examples of recepit inspection include dimensional checks, straightness, review of material test reports and sending out samples from each lot for mechanical testing and chemical analysis.

The only thing that you might contemplate is to do spot inspections to keep your supplier honest.
