Effects of Machining Process Parameters on Tool Wear

Exercise
The intent here is to show the relative effects of cutting speed, feed rate and depth of cut on tool life. Tool life is plotted as a function of these cutting conditions for typical values of n and C..

Task: Determine the relative importance of cutting speed, feed rate and depth of cut on tool life.
Click "Reset" to initialize,
Select a desired tool life, e.g., 90 minutes,
Experiment to obtain a set of cutting conditions that gives the desired tool life,
Run tests to determine relative importance of the machining process parameters and answer the questions below,

For example, change one variable and determine how much the other variables have to be changes to bring tool life back to the initial value.

Answer the following questions quantitatively and produce screen prints that show the answers to the questions.
a) If the feed rate is doubled, by how much (percentage) must the cutting speed be changed to obtain the originally specified tool life?
b) If the depth of cut is doubled, by how much (percentage) must the cutting speed be changed to obtain the originally specified tool life?
