時代の二ーズとタイミングがマッチ する商品開発の大切なことを物語っている
ほどなく、「互換式生産方式」の遂行にはノギスは欠 かせない存在となった
A社でノギスを用いたとき、嵌め合いの公差の設計基準を見直さなければならなかったという
設計に当たって真の公差はどのくらい必要なのか、本当の値の測定ができないと決められないことを物語る事実である
ネジを回転させながらその移動距離を測って物の長さを測定しようとする方法の実用化は、十七世紀英国のBに始まり、Cを経て、1805年のDに至る
Before long, vernier calipers became essential factor with executing "Compatible Product Method".
When A company used calipers, they had to review the criteria of designing tolerance for fitting.
This fact shows that really proper tolerance for designing cannot be fixed without measuring real numeric value.
Practical application of the way that measuring length of the object by measuring the migration length as turning a screw originated from B in Britain in 17th century, via C, reached D on 1805.
Before long, the vernier scale became indispensable in execution of 'compatible production method'.
When using a vernier scale from company A, a design criteria for fit tolerance had to be reviewed.
The fact is that according to design it couldn't be decided how much proper tolerance is needed, and real value could not be measured.
Method of measuring the lenght of an object while turning the screw and estimating distance of that movement was first implemented by B from Great Britain in 17 century, pass the C and reached D in 1805.
Before long , in the performance of " compatible type production system ", calipers became a necessary thing.
When Company A usee caliper, it had to review the designed criteria of tolerance of common difference
Do we really need a plan of tolerance, when we cannot determined it, is what we can tell when we can't decide in reality.
While rotating the screw, we can change the application of the method to measure the lenght of the distance that began in the seventeenth century in the British B Country, passed to C, till D in 1805.
Soon, the usage of vernier will have become a indispensable part of the execution of interactive method of manufacturing.
It was a true story that, if they were not able to measure the exact value, they were not able to decide how much the value of the real tolerance of fitting things together applying in the design, which has to be revised, shall be considered necessary when company A was applying the vernier.
The realization of the method to measure the length of a stuff by measuring the moving distance of the twisting screw thread,was started from the B of Britain in the 1600s, then further developed by C, and finally accomplished by D in 1805.
