To can cooperate cheek by jowl with the spare parts in rotate or moving point-blank, industrial group raised the requirement of sex of a few functions to a lot of spare partses. When the design the engineer blends in these requirements the spare parts in when, they will be right the flatness of the spare parts, circularity, columnar even degree set necessary tolerancepublic errand size, and cylinder is spent reflected the integral performance with flatness and both circularity. When when the design the engineer regards main factor as to consider flatness, the parallel that is apart from certainly through two apart commonly is linear, tolerancepublic errand range limitation is measuring plane in. Normally, the tolerancepublic errand district that carries whole face will decide flatness, for example will " flatness public errand is in certainly 0.

001in(1in=25.

In the limits of 4mm) . " major measurement technique is to build on linear or planar foundation. When measuring flatness, the circumstance is identical also. But when measuring flatness, do not need any data commonly, it undertakes metrical at the appearance of spare parts oneself relatively. Need certain thing to undertake comparative as datum line nevertheless. What what its need is fiducial and linear special and simple, can be a straightedge, also can be one serves as measure and more accurate used high measuring instrument or figuration machinery. Measure flatness the directest with the basiccest method it is the straightedge that uses to have certain precision. In a lot of application domains, use straightedge to undertake metrical to checking the surface, or using feeler or smooth unoccupied place law to measure interval can be accepted. Below the situation that did not measure equipment newlier, can use an accurate straightedge occasionally, will measure abrade surface through smooth unoccupied place law. Through good illuminant has observation, can see easily commonly under 0.

The light of 0001in is unoccupied place. When light unoccupied place when achieving 70~50 μ In, the light begins to become red. When light unoccupied place when achieving 30 μ In, the light becomes blue. Of the light become angry because radial diffraction is caused,effect is. This kind of method is very effective to checking these little spaces, but also existing a few problems, include the issue such as environmental problem and operation personnel change among them. Beauty of BB frost rank reduces weight which kinds in vain medical effect good beauty is white effective thin waist product is effective what neutral perfume is good with protect skin to go the it is better to have very much one is plant measurement technique of which brand can obtain black head better measurement result, this uses electronic height measuring instrument or figuration system namely. These two kinds measure instrument itself to be had taller measure precision. Accordingly, this kind of method is not to use straightedge and spare parts to undertake contrasting metrical, pass gauge however, have spare parts and an in-house fiducial face contrast. Measuring function and measurement technique basically of high measuring instrument and figuration machinery is identical. These two kinds of afore-mentioned measurement technique use an interior to measure fiducial mix to be passed as what measure exterior movement feeling measure a head, pass sensor to undertake comparative to measuring the change of the surface and fiducial surface. Both the outcome that the deviation between measures namely or the flatness that are the surface that be measured. After knowing this deviation is worth, can use tolerancepublic errand limits and the tolerancepublic errand measure that ask according to place, the surface of certain part measures an outcome. As other measurement the department consolidates model, the measurement that its use the requirement that the instrument must accord with a spare parts. The precision of some height measuring instrument is 0.

0002in, and a few otherer measuring instrument, include certain figuration system, their measurement precision can be achieved 0.

00001in. Its are passed feeling measuring a head can be the digital indicator with simpler structure, also can be more accurate digital coder probe. According to different high measuring instrument or figuration system, the amount of the measurement point on length of OK and comparative surface and this length, set all sorts of parameter. Fall in all sorts of circumstances almost, want Xiang Jifa to give a statement that start only, measure can begin immediately. Have line normalization is handled as the system, and automatically purify angle deviation, can show automatically measure an outcome. Measure the data of black and white image that is a flatness that be measured as a result finally, without the shadow of red or blue, the user can understand an outcome easily.
