A machining assistance method and an apparatus using the same are provided. The machining assistance method comprises following steps. Firstly, a circle correction path is received for driving a platform to perform a circular motion. Next, a driving torque of the server driver driving the platform is obtained. Then, whether the driving torque is changed to 0 is determined; if yes, a first position of the platform is recorded. Then, whether the driving torque is changed to a peak is determined; if yes, a second position of the platform is recorded. After that, the server driver is controlled to drive the platform according to a first position and a second position in a machining process.

A balance correction assistance device includes a storage unit that stores an attachment/detachment position, where a weight for adjusting the balance of the rotating body is attached and detached, and a predetermined operation position, where the weight for adjusting balance is attached to or detached from the rotating body: a rotation position information acquisition unit that acquires, from a rotation position detection unit, information indicating the rotation position of the rotating body: a determination unit that determines, on the basis of the rotation position, a rotation angle difference, between the operation position and current attachment/detachment position, in the circumferential direction of the rotating body: and a notification control unit that, if the absolute value of the rotation angle difference is less than a first threshold, issues, from a notification unit an audible notification indicating that the absolute value of the rotation angle difference is less than the first threshold.
