The piercing can be stably formed when forming holes, notches, external shapes, etc., which extend over the corner portions sandwiched between two surfaces.The cam device 20 redefines the piercing Pi1 of the corner portions R11 and R14 to the position on the surface S11 off the corner portions R11 and R14 by an indirect redefinition method for changing the direction, length, or approach angle of the approach AP 51.In this re definition, when the position of the piercing Pi1 cannot be defined outside the corner portions R11 and R14, the cam device 20 redefines the position of the piercing Pi1 by a direct redefinition method.In this re definition, the cam device 20 redefines the position of the piercing Pi1 previously, and then extends the length of the approach AP1 in accordance with the position of the pierced Pi1 which has been redefined.Therefore, when the hole H1 traversing the corner portions R11 and R14 is formed on the surface S11, the position of the piercing Pi1 can be prevented from being allocated to the corner portions R11 and R14.[Orig] 19b
