Abstract— that research gets to develop new operations for controlling forging defects. Rolling blocking finishing is used to complete forging operations in a standard procedure. In that study, successfully preventing some forging defects needed adding one more procedure during blocking and finishing. Certain products with uneven shapes, including suspension arms and y-arms, are generated during the forging process. As a result, flaws like twisting and bending arise. That study found that adding a new operation to the forging process helped control these kinds of errors. Because of the operation, coning operation flaws are also controlled, and the die life of coning operation is improved.
