Q1 the general process of reaming a hole with a lathe includ

Solution

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.
