The section steel is machined into various cross-sectional shapes depending on the purpose of use. According to this cross-sectional shape, the section steel can be classified into "L", "H", "c", "I" shape and the like.

The above-described various types of steels are cut in the longitudinal direction, chamfered in the edge region, marked on the surface, or punched to suit the purpose of use.

Various kinds of machinings performed on such a shaped steel are conventionally performed manually by an operator. For example, in the case of cutting, after measuring the size, the shaped steel base material is supplied to the manpower, and the cutter is pressed to cut.

At this time, an error may occur because the operator directly measures the length, and there is a risk of injury of the operator due to the reaction generated during cutting. In addition, since at least two or more personnel, such as one cutting man, one member of the steelwork for the cutting process is used for the cutting process, there is a problem that labor costs are increased and work efficiency is reduced.
