Normal > is in group by group mass-produced in, the measure that constant appliance has fixed measure will examine workpiece, this kind of measure is called gauge. The dimension on workpiece blueprint is the ultimate size that assures to have interchangeability. The gauge that measures work measure makes two limits measure normally, namely size of the biggest maximum and size of the smallest maximum. The gauge that measures smooth aperture or axis to use calls smooth gauge. What smooth gauge basis uses at measuring size of inside and outside is different, cent calipers and plug guage two kinds. Normal Align=center> pursues 1 calipers Normal >1. Calipers Normal > calipers uses the measure that measures the workpiece such as cylindrical, rectangle, polygon. If the graph is shown 1 times,calipers uses most form. If blueprint dimension of the axis is ¢80 Mm, the size of the biggest maximum of calipers is: 80 - 0.

04 ＝ 79.

Size of the smallest maximum is 96mm: 80, 0.

12=79.

79 of 88 Mm calipers.

96mm one aspect of the matter is called an end; 79 of calipers.

88mm one aspect of the matter is called end stop. Normal > is measured, if an end of calipers can carry work, and end stop cannot carry work, state workpiece is eligible; If an end of calipers can carry work, and end stop also can carry work, state workpiece size is too small, already became waste product; If connect end and end stop to cannot carry work, state workpiece size is too large, unqualified, must do poorly done work over again. Normal >2. Plug guage Normal > plug guage waits for inside dimension with the aperture that will measure workpiece, chamfer. It also make it is the biggest ultimate size and size of the smallest maximum two kinds. One aspect of the matter of its size of the smallest maximum is called an end, one aspect of the matter of size of the biggest maximum is called end stop, commonly used plug guage form is shown 2 times like the graph, the both ends of plug guage has a cylinder each, long cylinder one aspect of the matter is an end, short cylinder one aspect of the matter is end stop. When checking work, eligible workpiece shoud be able to carry an end and cannot pass end stop. Normal Align=center> pursues 2 plug guage CNC Milling CNC Machining
