Which of the following is NOT a desirable characteristic of
Solution
Ans:- Hydrophilic reaction with the surfcae of the workpiece is NOT a desirable characteristic of a cutting fulid.
Because :- A hydrophilic or portion of a molecule is one whose interactions with water and other polar substances. Cutting fluid properties can not be improve by polar additives.
Cutting fuliids must have some degree of corrosion protection. Ferrous metals rust rapidly because protective coating removed while machine operation.
Low cost always condisider to selection of cutting fluid.
Hydrophobic effect of cutting fluid is responsible for the separation of a mixture of oil and water. So it a required properties of cutting fluid.
Hense , Hydrophobic effect , Corrosion resistance and Low cost are the desirable characteristic of a cutting fluid.
