The 1st Educational Article -The Co-ordinate Measuring Machine (CMM) is a relatively young operating unit, if compared with other kind of equipment such as Machine Tools; as a matter of fact the CMM was invented in the early sixties, since then it has become an indispensable part of any manufacturing process. The CMM is obviously utilised to “measure” in the sense that it is capable of detecting the position of points in the space with very low uncertainty
The 2nd Educational Article (Part 1) -Any Co-ordinate Measuring Machine (CMM) is fundamentally based on the use of four technological elements which, once integrated and brought in the condition of interacting, constitute the CMM itself..
The 2nd Educational Article (Part 2) - Generalities - The better definition of a Numerical Control for an automatic Co-ordinate Measuring Machine is “Data Handling and Control System”. This definition is rather accurate because derives from the fact that the system in question allows to manage besides, the dynamic activities of the CMM, also the computing the programming and interfacing tasks.
The 2nd Educational Article (Part 3) The Sensors - The function of a Co-ordinate Measuring Machine (CMM) is the acquisition of information on the measurand; generally under form of Cartesian co-ordinate values. The devices utilised to explore the part in order to generate such information are the “Sensors”; as underlined in the 1st article one of the four fundamental components of a CMM.
The 3rd Educational Article - Premise: The working group (WG) “Specifications” is one of several working groups of ia.cmm, the International Association of Co-ordinate Measuring Machine Manufacturers. This working group is active in the area of CMM specifications. The performance specifications for CMM’s are defined by the ISO 10360 series. Based on ISO 10360-1, the “Specifications” WG has generated a structure for a common data sheet within all associated Companies
