Explanation / Answer
Q# 1}
theoritical background-
*grinding - in this process grinding wheel as a tool is used for abrasive machining process it is subset of cutting
*milling - in this process rotary cutters are used to remove material from workpeice
*lapping - in this keeping abrasive between two surfaces are rubbed together
*boring- in this process already drilled holed is enlarged
ANSWER-
reaming of hole - this means to enlarge the hole by small amount but by high degree of accuracy.
hence, Reaming a hole with lathe machine includes boring(option 4)
Q# 04}
theoritical backgroung
excessive - beyond the limits.
hardening- it is process of increasing hardness by increasing resistance to plastic deformation.hardening failure is failure due to increased hardness of object to be milled.
Cratering- Cratering is caused by a combination of diffusion and abrasive wear in inserts. Heat build-up in the workpiece chip causes elements to dissolve and diffuse into the chip, creating a crater.which leads to failure.
splattering- to splash and scatter upon impact on object of coolant leading undesirable results.
clogging-to become blocked or filled so that movement or activity of tool is resisted(typically by formed chips)
ANSWER-
EXCESSIVE is not a mill cutter failure.
