Question

Problem Set A company that manufactures can-forming equipment wants to set up an experiment to help understand the factors influencing surface finish on a particular steel subassembly. Three factors were chosen to be varied in the experiments. The factors were: 1 Low LevelHigh Level Factor Name A - RPM B - Feed Rate C Tool Radius 588 .004 1/64 1182 .008 1/32 a) Generate a tree diagram which represents the possible combinations of a full factorial at two levels. b) Generate a design matrix representing the possible combinations c) Suppose changing the tool radius requires an 8-hour teardown procedure. Discuss strategies for limiting the number of times tool radius must be changed. Suppose the part being machined is 4130 preheated steel. The part is a 1" diameter rod which is 4" long. Should the part be measured at one point or several points? Discuss various d) approaches for making multiple measures on the part.
