Which turning operation and which workpiece surface is possible to machine with the shown cutting tool?
Carbide-based cermets, i.e. carbide tools are used in cutting tools in a following manner:
In the turning process following movements are used:
There are following motions when drilling:
During machining processes plastic deformations spread in following places and cause following effects:
Schaeffler diagram allows
Preheating of the weldable components results in:
Calculate Hot Cracking Susceptibility(HCS) for a steel with following chemical composition:
C = 0.2Si = 4.7Mn = 0,84P = 0,035S = 0,012Cr = 0.6Mo = 0,32Ni = 0,99Cu = 0,11V = 0,040
Provide the answer with 1 decimal place accuracy.
Calculate Carbon Equivalent (CE) of the steel. The chemical composition of the steel is as follows:
C = 0.3%Si = 0,4%Mn = 0,69%Cr = 1.2%Mo = 0.3%Ni = 1.6%V = 0%W = 0%P = 0,034%S = 0,01%Cu = 0,2%
Write the answer with accuracy of two decimal places. Use "." as decimal separator.
The critical value of carbon equivalent is...
