Question

Define machinability. Compare the machinability of acrylic material with the metal materials. Define Toughness. What does Toughness of Material Indicate? What is Tolerance and why is it important when making products. List the 3 different of tolerances. What is GD&T? Why it is important

Answer 1

Machinability + machinability is the case with which a metal can be cut or machined. pesemitting the removal of the material with a satis. 110 factory finish at low cost. Material with good machinability requine little power to cut. + comparision of Acrylic machinability & metal machinability Acrylic is a lightweight thermoplastic which has high hardness, tensile strength compare to that of Hardness metals. 2. So machinability of acrylic required power to that of metal high machining 3. It is pretty well impossible to machine acsy lic & get an optically clear finish to that of metal palets 4. To get higher surface finish we required diamond machining on really fancy machines, while we get goot surface finish without diamond machining for metal part, 2 Toughness:- material to absorb. Toughness is the ability of a energy and deform plastically ou ithout Angcturing

Toughness indicate the load bearing capabilities of material with flaws. by the It also indicate the resistance offered material to fracture whien stressed a + The key to toughess is strength & and dustripty good combination of © what is Toletance & why it is important. → Tolerance is the acceptable range for a physical dimension, which is determined by the product designer based on form, fit & function of the part, & Tolerance in manufacturing products. because it determine hoco well a part will fit in the final piece and how reliable the final final product will work + when manufacturing the parts 9t's not possible to manufacture moy the paret lopto of given dimension accurately is essencial will

се that's why apply tolerance to the to the part upto given limit where PL will work, same that of given dimension. as -0.09 i list 3. different of tolerances. limit dimensions, pi) unplateral Pip bilateral tolerance 40,09 1000 limet dimensions are two dimensional values stacked on top of each other. It shows the smallest and the largest values allowed 20.05 1.3000 -0.16 unilateral dimensions are dimensiondl values in which target dimension is given along with a tolerance that allows variation to one dien. acure in only A bilateral tolerance exists of the variation from e target dimension is shown occuring in both the positive & negative direction. © What is CD & T? why it is important. CODUIT means Geometric Dimensioning and Tolerancing. a language of symbols and standards designing designed and used by manufactures to describe a a product and facelitate communication between entites aorking together to produce something engineers and
