Are the cast pieces cylindrical, or spherical? What are the thicknesses?
Usually the cast pieces are a little oversized so that when they cool, they will fit.
What is the temperature of the cast pieces when the ID measured 187mm?
The force required to "squeeze" them from 187mm to 180mm ID will depend on the thickness of the pieces. The thicker they are, more force will be required.
Are you studying in mechanical engineering, or is it a real-life problem? It sounds to me that some data are missing.
I have to correct the Internal diameter of 2 half round cast piece of aluminuim against the actual mandrel. Because after casting the pieces are open when cooling.i will use chain block to correct or tie the cast piece with the Mandrel. could you please help me to find out what will be force to apply to make it correct. is there any particular formula? eg: the required I.D is 180mm the cast pieces are now 187mm. so i have to round it with the mandrel which is 180mm dia and will use chain block to tighten it with force. just i wnat to know what is the force will be there to correct it.?

Reply: thanks for the answer: more details as per your question. The thick ness of the cast piece is 50mm and the straight length is 400mm ; means the product dim is 400mm long x 50mm thk x 180mm i.d and 280mm O.D - in 2 halves. hope this data will satisfy to give more details to me against my question.
