A deformation processing support system acquires target shape data of a work having a reference line; acquires intermediate shape data from the work in an intermediate shape having a reference line marked thereon; and overlaps the two data on each other by aligning the reference lines relative to each other, to calculate a necessary deformation amount of the work based on a difference between the two data overlapped on each other. To align the reference lines with each other, first and second alignment axes with the same length calculated for the respective reference lines are superimposed on each other. Subsequently, the intermediate shape data is relatively rotated with respect to the target shape data around the first alignment axis.

A deformation processing system acquires target shape data of a work including a reference line, acquires intermediate shape data from the work having an intermediate shape having a reference line drawn thereon, puts these two pieces of data side by side by positioning the reference lines relative to each other, and calculates a necessary deformation amount of the work based on the difference between the two pieces of data put side by side.

A spinning forming method includes: preparing a plate including a back surface at which a ring-shaped projection is formed along an outer peripheral edge of the plate, a ratio of a thickness at a reference position of the plate to a thickness at a tip end of the projection being 0.7 or less, the reference position being a position where an inclination of a portion of the back surface which portion extends toward the tip end of the projection is 45° or more; rotating the plate; moving a processing tool outward in a radial direction from an inner side of the projection to a position above the projection while pressing the processing tool against a front surface of the plate that is rotating; and locally heating a portion of the plate against which portion the processing tool is pressed.

An apparatus for steering a metal pipe during a roll grooving process including a clamp to be secured to a static structure of a grooving press spaced apart from a rotating cylinder of the grooving press, a pair of spaced parallel rods slidably disposed through spaced openings of the clamp, a handle affixed to first ends of the pair of spaced parallel rods distal from the rotating cylinder, and a guiding tool affixed to second ends of the pair of spaced parallel rods proximate to the rotating cylinder carrying spaced rollers adapted to contact an outer surface of a metal pipe during a roll grooving process to apply a force against the metal pipe. A method for applying a force against a metal pipe during a roll grooving process.

A method for incrementally forming includes: preparing a tool T disposed on one side of a metal plate W, a fixing jig 1 to hold a periphery of the metal plate W, and a template P1 including a molded edge E that follows at least a part of a contour of a part to be processed F; arranging the template P1 on the other side of the metal plate W; holding the periphery of the metal plate W together with the template P1 by the fixing jig 1 to fix the metal plate W and the template P1; and moving the tool T while pressing the tool T against the metal plate W, to incrementally form the part to be processed F having a three-dimensional shape of the metal plate W.

The method enables to form the part to be processed F in high precision with no use of a molding die and thus, is effective in bringing about reducing cost of equipment and manufacturing.
