Question

U MUST DO THIS PROBLEM 5. A 2 experiment determined a cutting tool's useful life for different cuting specs run in a complete 2 cutting angle (C). Two levels of each factor were chosen and two replicas o design. The tool life results are summarized in the following table usihe 2 Full Factorial Experiment hardness (B) and s were run in a complete 2 factorial order for common notation: Combination Replicate I Replicate 11 320 407 351 473 Parti 208 347 545 598 389 457 512 425 al input and output from DOE software is given below. Fill in all the blanks. Combination Replicate I Replicate II 221 212 406 389 112 122 347 425 351 Sum Sqdf Hean Scg F-ratio -13.8 0.5590 0.0421 0.0013 0.37 756.3 11881.0 47961.0 484.0 56.3 54.5 47961.01 0.0009 53824.0 AC BC ABC -26.8 0.10 0.7561 2035 Error 16281.0 TOTAL 134259.8 15 CHECK (V) ALL EFFECTS THAT ARE SIGNIFICANT at the 5 level cutting speed x Metal Hardness- Cutting Speed (Factor A) Metal Hardness (Factor B) Cutting Angle (Factor c) -cutting Speed x Cutting Angle Metal Hardness x Cutting Angle Cutting Speed x Metal Hardness x Cutting Angle YOU CANNOT SKIP THIS PROBLEM

Explanation / Answer

Decision rule : if p value < 0.05, then variable is significant

Variable p value Decision Cutting speed(A) 0.5590 Not significant Metal hardness(B) 0.0421 Significant Cutting Angle(C) 0.0013 Significant AB 0.6389 Not significant AC 0.0009 Significant BC 0.2697 Not significant ABC 0.7561 Not significant
