In order to 1ransport the steel roll coil effectively and safely to the destination, the stability of the steel roll coil which induced the minimum movements during the 1ransportation was s1rongly required. The basic 1ransportation equipment for the steel roll coil such as the wedge is made of 100% imported wood known as the apitong. However, the material characteristic such as the rigidity has caused permanent damages to the steel roll coil and the damaged steel roll coils were not easily restorable. Thus it was unsuitable for other purposes. The introduction of new materials to manufacturing wedges which would have a good recovery performance and thus enable the wedge prevention or reduction to the steel roll coil or any other products during the 1ransportation is needed. Due to the fact that recovering damage of the coil is almost impossible, we have to find the new type of wedge that can substitute the apitong wedge. Therefore, we are going to develop a wedge that does not damage rolled steel coil and has better recovery and softness than existing apitong wedge.

This paper wishes to develop system that measure an external diameter of optical-ferrule and roundness that is optical connection parts that is necessary in optical communication net construction that increase rapidly present automatically and plan productivity elevation and personnel expense curtailment. There is LC, PC, MU, and so on various form in the case of optical-ferrule and Recently, ferrule that have special form is appearing. Hereupon, can bring cost reduction by productivity elevation, measurement quality elevation, number of persons attrition and parts loss amount decrease etc. by computerizing measurement work of examination process that depended on existing manual processing by developing exterior diameter of LC ferrule and roundness' measurement system. Also, use of LD and PD ferrule by country and universal FTTH business is increasing, and LC optical ferrule that is necessary to laser packaging of inside depends on income. Therefore, productivity improvement of LC ferrule can contribute in could do to maximize income substitution effect country industry development. But, manual processing dependence of examination process that it selects LC ferrule manufacturing process defective goods that productivity does not increase because is high productivity elevation decrease bring. Therefore, productivity elevation of LC ferrule wishes to solve productivity decrease by existent manual processing computerizing external diameter and roundness measurement examination process.
