CSSBB · Question #250
Which statement(s) are correct about the Factorial Plot shown here? (Note: There are 3 correct answers).
The correct answer is A. When the cutting speed increased from low to high level, the tool age increases B. The coefficient of the metal hardness is positively related to the output of tool age C. The coded coefficient is lower for cutting speed than the cutting angle related to the output of tool. See the full explanation below for the reasoning.
