在修理汽车时,经常需要在车床上改制一些加工余量极少的零配件。如在 C 618车床上加工,因刻度精度不够,很难车到精确尺寸。后来我们根据三角函数的关系,把小拖板摆成不同的角度来调节进刀量,解决了刻度精度不够的问题。 When repairing a car, it is often necessary to restructure some spare parts with minimal machining allowance on the lathe. As in the C 618 lathe processing, because the scale accuracy is not enough, it is difficult to car to the exact size. Later, according to the relationship of trigonometric function, we put the small pallet into different angles to adjust the feed rate, which solved the problem of insufficient scale accuracy.
