MEASURING CLASS SOME MEASURING TIPS for the BOX TYPE COMPONENTS
The box type components required high accuracy.And with more measurements,it probably covers the parameters of geometric dimensions,flatness,parallelism,coaxiality,perpendicularity,and the spacing of holes on different coordinate axes,etc
The box type components required high accuracy.And with more measurements,it probably covers the parameters of geometric dimensions,flatness,parallelism,coaxiality,perpendicularity,and the spacing of holes on different coordinate axes,etc.Therefore,the well preparation should be arranged before measuring,which could improve our measuring level.Meanwhile,it is also the reference for other measuring.
1.Select the correct measuring standard
As it is known,machined parts processing bases on the standard of design,processing and measuring.Before measuring,a well understanding of the design standard,processing standard is necessary.And it is suggested that the measuring standard,design standard and processing standard are on in the same criterion.If it is necessary,it is also suggest that all designers and processing engineers have a seminar to discuss and communication before the measuring.
2.Guarantee the effective measuring accuracy
Generally,the measuring accuracy is up to the accuracy of the stylus.The when recommending the stylus,the measuring accuracy is priority.The option of stylus and the lengthening bar should base on the construction characters of the components.After the calibration of the stylus,the calibration of each direction should also be inspected to guarantee the accuracy.
3.Ease of measurement
One hand,it is suggested that the calibration of the stylus should be done within one time for the convenient using.On the other hand,to guarantee the stylus can measure the measured factor and position.Such as,the more deeper hole and steps exist between the box type components,so when it should make sure these stylus could reach these measured position.
4.The proper clamping parts
We should select the proper clamping tools and methods according to the the characters of shapes&constructions of components and the measuring requirement to guarantee the measuring machine could work in the effective range.Some more attention below should been paid when clamping the parts.First,do not clamp the parts at the datum feature to ensure that all measured elements are accessible.Second,do try to reduce the deformation of the clamping parts considering the measuring force and ensure the no slight movement in the measuring process
Generally,three coordinator measuring machine is ideal for the measuring of the box type components,and it could meet the measuring requirements for the methods and accuracy.For the batch measurement,after reviewing the drawing,we choose the proper measuring proposal&clamping parts,which improve the measuring efficiency greatly.
