Title:
MACHINING METHOD
Document Type and Number:
Japanese Patent JPH01115535
Kind Code:
A
Abstract:
PURPOSE:To ensure required dimensional accuracy with respect to reference or other machining position by securing a work to a pallet through a plurality of clamp means and releasing some clamp means prior to finish work. CONSTITUTION:If the surface accuracy of a fitting face 8 is not sufficiently high when a differential carrier 1 is machined in a machining line, distortion may occur in the differential carrier 1 when a flange section 11 is pushed against a seat member 22 through a clamp device 23 to displace wall sections 5, 5, and machining positions of bearing sections 3, 3 are shifted when finish work is carried out. If one clamp device 23 is released after rough work of the bearing sections 3, 3, distortion caused by pushing the entire circumference of the fitting face 8 having insufficient surface accuracy forcibly against the seating member 22 can be eliminated. Consequently, offset can be confined within a predetermined error range when the differential carrier 1 is removed from a pallet 20 upon finish of work.
