Abstract
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.
Existence of research evidence correlating sand-grain finish with cast surface finish is compatible with the range of 60 to 300 AFS grain-finish sand mixtures used in the experiment. Further research evidence correlating alloy-hydraulic pressure with casting finish is addressed with use of pressure heads ranging from 0.2925 lbs. per sq. in. to 3.0586 lbs. per sq. in.
