Cutting Fluids

Question 1

What are the aims in metal cutting?

Answer 1

The aims in metal cutting are to retain accuracy, to get a good surface finish on the workpiece and at the same time to have a longer tool life.

Question 2

How is heat generated in the metal cutting process?

Answer 2

However during the metal cutting process heat is generated due to:
the deformation of the material ahead of the tool friction at the tool point

Question 3

How can heat generated due to friction be reduced?

Answer 3

Heat generated due to friction can readily be reduced by using a lubricant. Heat caused by deformation cannot be reduced and yet it can be carried away by a fluid. Thus the use of a cutting fluid will serve to reduce the tool wear, give better surface finish and a tighter dimensional control.

Question 4

How can heat caused by deformation be reduced?

Answer 4

Heat caused by deformation cannot be reduced and yet it can be carried away by a fluid. Thus the use of a cutting fluid will serve to reduce the tool wear, give better surface finish and a tighter dimensional control.

Question 5

What do cutting fluids do?

Answer 5

Thus the use of a cutting fluid will serve to reduce the tool wear, give better surface finish and a tighter dimensional control.

Question 6

What are some of the safety hazards with cutting fluids?

Answer 6

Rancidity –Coolant must be replaced regularly as constant heating and cooling makes it go off quickly

Irritant-can be an irritant to the skin and eyes. Contact with skin may cause dermatitis( skin disease)–Barrier cream is used as a prevention method.

Question 7

How are cutting fluids a hazard in the classroom?

Answer 7

Skin irritant, slip hazard,
