Question 1 Thelematerial_mr.csvlocatedinthe/examples/foldercontainsinformationthenameandthemachinability rating for multiple materials. Remember that material rating is given as a percentage. A material_mr.csv le with two materials would look similar to the following: Titanium, .21 Stainless Steel, .45 Class les H2_Q1.java and MRData.java are provided for you as a starting point and are located in the /src/studentWork folder. Modify the code in both les to accomplish the following: a. Read in (using OpenCSV) both the name and machinability rating for each material. b. Calculate the cutting speed for each material using the information provided and the fact that the cutting velocity for B1112 Steel is 165 surface feet per minute. c. Output the cutting speed for each material to the console with material name.

Question 2 The le material_ttle.csv located in the /examples/ folder contains , in the following order, the name, cutting speed (v, suface feet per minute), tool life (T, minutes), and Taylors (C) constant for multiple materials. A material_ttle.csv le with two materials would look similar to the following: Partial Concrete, 80, 10, 50 Fragmented Steel, 100, 20, 75 Class les H2_Q2.java and TTLEData.java are provided for you as a starting point and are located in the /src/studentWork folder. Modify the code in both les to accomplish the following: a. Read in (using OpenCSV) the name, tool life, constant (C) and cutting speed values for each material. b. Determine the constant n for each material. c. Output the value of n for each material to the console with material name. Question 3 The le wear_test.csv located in the /examples/ folder contains information regarding a wear test done on an unknown material. The wear test consisted of two dierent experiments in which the material was cut at speed vi and cutting continued until the time of tool failure Ti (where i = 1,2 and i is the experiment number). Note that v and T are two of the parameters found in Taylors Tool Life equation. For example, an experiment with T1 =15, v1 =50, T2 =3, v1 =80 would have a wear_test.csv le that looked as follows: 1 15, 50 3, 80 Class les H2_Q3.java and WearData.java are provided for you as a starting point and are located in the /src/studentWork folder. Modify the code in both les to accomplish the following: a. Read in (using OpenCSV) the velocity (v) and tool life (T) for both experiments. b. Use the four values read in to determine both n and C (from Taylors Tool life equation) for this unknown material. c. Output the value of n and C for the unknown material to the console.
