摘要： An object of this invention is to generate NC (Numerical Control) data to improve efficiency of machining. This invention comprises the steps of: generating NC data to machine a first portion of an object, wherein the first portion is specified based on a supposed cutting load distribution of the object; and generating NC data to machine the object after the first portion of the object was machined. Thus, at least two-phase machining data is generated which is separated based on high or low of the supposed cutting load, for example. That is, a tool machine processes the object stepwise. Therefore, it becomes possible that a portion is machined in advance, that it is determined that it is better to machine beforehand based on the supposed cutting load distribution, and the object after the machining is separately machined.

摘要： A high-magnification zoom lens having a lens system that is movable from a wide angle setting to a telephoto setting includes five lens groups. The lens system has a focal length of fW in the wide angle setting and a focal length of fT in the telephoto setting. The five lens groups are arranged in order from an object side along an optical axis that extends from a center of the lens system. A first lens group G1 has a positive refractive power and a focal length of f1, a second lens group G2 has a negative refractive power and a focal length of f2, a third lens group G3 has a negative refractive power and a focal length of f3, a fourth lens group G4 has a positive refractive power, and an image composing lens group GR has a positive refractive power. When the lens system changes from the wide angle setting to the telephoto setting, the first lens group G1 and the fourth lens group G4 move such that a distance between the first lens group G1 and the second lens group G2 increases, a distance between the third lens group G3 and the fourth lens group G4 decreases, and several conditions are satisfied.
