Q3 (a) Describe the major independent and dependent variables that influencing cutting process
(b) A 150 mm long with 12.5 mm in diameter of a stainless steel rod is being reduced in diameter to 12.0 mm using a lathe machine. The machine spindle rotates at 400 rpm, and the tool is traveling at an axial speed of 200 mm/min. Determine;
(i) cutting speed
(ii) material removal rate, and
(iii) cutting time
(c) Briefly describe and differentiate between the melting process, pouring process and solidifying process in metal casting.

Refresher on Variables:
Classifying variables as independent or dependent:
The independent variable is the one being
manipulated or grouped in the study for comparison. A tip to
remember this is to think that independent starts with “I” and I,
the researcher, manipulate that variable or have control over who
is grouped in the study. The way we will be using independent
variables in this course is in terms of between group analysis, so
our focus will be on groups being...

Once the independent and dependent variables are identified correctly, regression analysis is often thought of as a Three Step Process:
Once the independent and dependent variables are identified correctly, regression analysis is often thought of as a Three Step Process:
What is the conclusion of the null hypothesis, Ho: B1=0;
If there is an association between X and Y, how strong is this association?
What are the values of the regression coefficients?
How would you explain this three step process to someone who has no knowledge of regression analysis?
