A Study Of Nonferrous Casting Surface Finish Using Statistical Theory And Computer Technology, D. C. Ekey
Robins School of Business White Paper Series, 1980-2022
This research is based on statistical research methodology to evaluate variation in casting surface finish in nonferrous production operations.
The Data Base of 82 cast surface finish measurements were produced in three U.S. foundries. The data base is comprised of two sub-groups. One data sub-group has a sample size of 58 aluminum cast surfaces. The second data sub-group consists of 24 cast bronze surface finishes.
The research is a continuation of preceding research with Gray Iron Castings. A macro operational level, rather than a micro laboratory level is used. The results substantiate the primary objective to help improve casting quality …

Inferential Operations Research On Surface Finish Of Castings, D. C. Ekey
Robins School of Business White Paper Series, 1980-2022
This paper reports the result of an experiment using statistical research methodology to evaluate previous findings, identify new effects and focus on potential future research efforts to improve the control of casting surface roughness.
The objective of developing a functional equation to predict casting surface roughness was achieved. A reliable and valid methodology for obtaining operational "surface imprints" of casting surface roughness was developed.
Gray iron castings within a weight range of 1 to 7000 pounds were studied. The population of 142 surface roughness measurements came from five foundries in the northeast regions of Pennsylvania, Vermont, Maine, and Massachusetts. The …
