Embodiment Construction

[0038] The equal division measurement method of the cylindrical cam profile curve of the cigarette machine of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0039] The measuring machine used is: Italian SCIROCC0RECORD, the measuring software is PC-DMIS 3.7 and 1UTOR, the accuracy is: 1.9+3L / 1000μm, the two sets of measuring systems are running under WINDOWS XP, and the DEAPPL language programming in TUTOR is used to realize the measurement automation.

[0040] First, establish a measuring coordinate system on the cylindrical cam surface.

[0041] Such as Figure 4 and Figure 5 As shown, the measurement coordinate system is established in the surface of the measurement part, the origin is established at the center of the camshaft, the establishment of the coordinate axis is determined by feature elements such as positioning holes, and Z=0 is set on the end surface.

[0042] Secondly, the profile surface of the cylindr...
