Need little help in the set ups of each formula.
A compacted body of iron powder is sintered into a 20mm-diameter, 45-mm-tall cylinder which, upon weighing, is found to have a mass of 98g. Calculate the apparent density, the percentage of theoretical density, and the void volume (porosity) in percent.
Need to quantify the relationship Ra = C1* s^C2 v^C3 Re^C4
this is for my lab report on effective maching of surface roughness using a lathe. we have been asked to quantify Ra = C1* s^C2 v^C3 Re^C4 where Ra is surface roughness, s is feedrate, v is cutting velocity and Re is the nose radius of the tool. we have performed experiment to get values of Ra for combinations of different v,s a ...continues
Please answer the following questions: Certain manufacturing processes have the following characteristics described below. Please characterize the process in terms of : Type of process, state of workpiece material and the type of process energy used. 1. A metal is cast into a mold and solidifies 2. A metal bar is reduce ...continues
1. Explain why studying the types of chips produced is important in understanding cutting operations. 2. Tool life can be almost infinite at low cutting speeds. Would you recommend that all machining be done at low speeds? Explain. 3. Explain the consequences of allowing temperatures to rise to high levels in cutting? 4. What ...continues
1. Explain the factors involved in selecting the appropriate type of abrasive for a particular grinding operation. 2. What are the consequences of allowing the temperatures to rise during grinding? (Q. 25.38). 3. What are the implications of using a smaller abrasive grain size (higher grit number) in a bonded grinding wheel? ...continues
17.22 - Describe the relative advantages and limitations of cold and hot isostatic pressing. 17.27 - should green compacts be brought up to the sintering temperature slowly or rapidly? Explain your reasoning. Please see attached.
Introduction to Manufaturing Process - Question 1
1) Calculate the 0.5Tm temperature for Zn,Cu, and Ni. Explain on this basis whether significant creep of these metals should be expected at 200 degrees C. (ISBN 0-07-116911-3) (page 119)
Introduction to Manufaturing Process - Question 2
2) Under otherwise identical conditions, would a melt heated to 1.2TL give a finer-grained casting than one heated to 1.1 TL? Give two reasons for your answer. (0-07-116911-3)
Introduction to Manufaturing Process - Question 3
3) A gear blank has been successfully hot forged on a mechanical press in a closed die. At the beginning of a new production run, the die burst. What is the likely cause? (ISBN 0-07116911-3) (chapter 9)
Introduction to Manufaturing Process - Question 4
4) A flat bar is to be rolls but the rolls refuse to bite (the bar is not drawn into the roll gap). State at least two measures that could be taken. (ISBN 0-07-116911-3) (chapter 9)
