18、a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represent
19、ed on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are dra
20、fted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International St
21、andard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 25178-601 was prep

32、d by the areal reference guide of the instrument; Z-axis is in the plane of the stylus trajectory and is perpendicular to the (X,Y) plane (see Figure 1) NOTE Normally, the X-axis is the tracing direction and the Y-axis is the stepping axis.

NOTE The measurement loop will be subje

36、esidual correction error difference between the value of a quantity obtained after correcting the systematic error and the real value of this quantity NOTE The residual error is composed of random errors and uncorrected systematic errors.

37、ghts reserved 33.2 Terms and definitions relative to lateral scanning system 3.2.1 lateral scanning system system that performs the scanning of the surface to be measured in the (X,Y) plane NOTE Typically, the lateral scanning system is composed of the drive unit X (3.2.3) and drive unit Y (3.2.4).
38、3.2.2 areal reference guide component of the instrument that generates the reference surface, in which the probing system (3.3.1) moves relative to the surface being measured according to a theoretically exact trajectory NOTE In the case of areal surface texture measuring instruments, the reference
39、guide establishes a reference surface (see ISO 25178-2). It can be achieved through the use of two perpendicular reference guides (see ISO 3274:1996, 3.3.2) or one reference surface guide. 3.2.3 drive unit X component of the instrument that moves the probing system (3.3.1) or the surface to be measu
40、red along the reference guide on the X-axis and provides the horizontal position of the stylus tip in terms of the lateral X coordinate of the profile 3.2.4 drive unit Y component of the instrument that moves the probing system (3.3.1) or the surface to be measured along the reference guide on the Y
41、-axis and provides the horizontal position of the stylus tip in terms of the lateral Y coordinate of the profile 3.2.5 lateral position sensor component of the drive unit that provides the lateral position of the pivot NOTE 1 See Figure 2 for the definition of the pivot. NOTE 2 The lateral position
42、can be measured using, for example, a linear encoder, a laser interferometer, or a counting device coupled with a micrometer screw. 3.3 Terms and definitions relative to the probing system 3.3.1 probing system surface texture component of the instrument consisting of the stylus (3.3.4), the pivot, t
43、he probe (3.3.2) and the digitizing system (3.3.3) NOTE 1 The axis of rotation around the pivot is parallel to the Y axis. NOTE 2 The probing system is commonly called a “pick up”. 3.3.2 probe surface texture device that converts the height into a signal during measurement NOTE In earlier standards
44、this was termed a “transducer”. 3.3.3 digitizing system device which converts analogue signals into digital ones NOTE 1 The digital signal as a function of the x and y coordinates forms the extracted mechanical surface.

45、 2 The digitizing system should not cause any intentional surface modification. NOTE 3 In a typical system, the digitizing system is usually an analogue to digital converter. 3.3.4 stylus mechanical device consisting of a tip and an arm NOTE The typical stylus is shown in Figure 2. Key 1 stylus tip
46、H height of the stylus 2 pivot rtipradius of the tip L length of the arm cone angle of the tip NOTE The above design is the most common. Other designs are also used, e.g. flexures, linear probes, etc. Figure 2 Characterization of the typical stylus 3.3.5 error due to arcuate motion vector error gene
47、rated by the rotation of the stylus (3.3.4) around the pivot See Figure 3. NOTE 1 The vector error consists of a lateral and horizontal component. NOTE 2 The arcuate motion generates an error of the measured profile. NOTE 3 The horizontal error which results from the arcuate motion is a function of
48、the vertical displacement and may be neglected depending on the required accuracy. NOTE 4 The probe only measures one quantity (typically Z or the angle of the stylus arm) which does not give enough information for the assessment of both X and Z quantities. The knowledge of the stylus geometry and e
49、ither X or Z quantity allows this assessment by using a mathematical adjustment.
