Chip breaking report. Final report
There is a desire to automate the precision finishing machines so that effective personnel/process isolation and minimum manhours per part could be achieved. At the current time, chip control requires that a machinist be present at each spindle to collect and remove the stringy, continuous chip that is formed during normal single-point-turning finishing cuts of several tough materials. This situation presents the single greatest restriction preventing both more process automation and enhanced personnel protection. Anyone who has ever washed his driveway with a garden hose stream knows that useful work can be accomplished with the flow stream. Industry has been using the energy of a hydraulic stream to break the normally occurring continuous uranium chip into short, freely removable and transportable segments for some time. The cutting fluid used in conventional machine tools can be similarly used to break and remove chips. The problem becomes one of appropriately understanding and applying the hydraulic energy to accomplish a large range of applications from thick roughing cuts through thin finishing cuts on materials which range from brittle through very tough for all of the normally encountered cutting geometries. This is desired if reliable fully automated cutting operations are to be successfully used. The purpose of this document is to summarize the status of the conditions under which chips can be effectively broken using both conventional hydraulic and alternative chip breaking schemes. Our purpose is to describe the methods and their effectiveness in as simple as possible terms. Specifically, we have evaluated there effectiveness as applied to hemispherical finish machining of uranium and stainless steel components.
