Sharp internal corner of the casting also causes the misrun defect in the casting.
View Answer Explanation
To avoid sharp external corners in casting design, rounding of external edges is done in pattern making that termed as radii.
Finishing allowance to a pattern is generally provided to avoid various defects in the casting.
Finishing also includes removal of scales from the surface of the casting.
Subsequent machining for products finishing does not require extra material to the metal casting, as it removes negligible amount of material from the casting.
Which of the following ranges show the approx range of finishing depth (in mm) required for finished casting?
For finishing allowance, great care is taken while adding extra material to the molten metal.
Which of the following parts is used to keep the casting in for reducing the finishing allowance?
Which of the following technologies is used in metal casting for reducing the product development time?
After providing the finishing allowance to the metal casting, it is not necessary to include shake allowance as it can be covered by finishing allowance.
A Fillet is provided in the finishing of a pattern which is very small for shallow castings.
