PROBLEM TO BE SOLVED: To shorten the pallet changing time by switching the acceleration when moving various kinds of pallets according to the work of individual works of various kinds of weight. SOLUTION: In a pallet turning method in a pallet changing device, a work of the maximum loading weight wmax is placed on a pallet in a preparing step to measure the maximum current value Imax when the work is moved at the predetermined acceleration a0 , a work of weight wn lighter than the maximum loading weight wmax is placed on the pallet to measure the maximum current In when the work is moved at the predetermined acceleration a0 . Various kinds of acceleration are obtained so that the maximum current In when the work of the light weight wn is moved at the predetermined acceleration a0 is equal to the maximum current Imax to the work of the maximum loading weight wmax . In the work machining step, the work of the maximum loading weight wmax and the work of the weight w not exceeding the maximum loading weight wmax of the work are placed on the pallet. The individual works are turned at various kinds of acceleration a so that the maximum current I when the individual works are moved is equal to the maximum current Imax to the work of the maximum loading weight wmax .
