Foreword

GB/T 16462 "CNC lathe and turning center inspection conditions" is divided into eight parts. --- Part 1. Horizontal machine geometry accuracy test; --- Part 2. Vertical machine geometry accuracy test; --- Part 3. Inverted vertical machine geometry accuracy test; --- Part 4. Linear and rotary axis positioning accuracy and repeat positioning accuracy test; --- Part 5. Feed, speed and interpolation accuracy test; --- Part 6. Precision test precision test pieces; --- Part 7. Evaluation of the contour characteristics in the coordinate plane; --- Part 8. Assessment of thermal deformation. This section GB/T 16462 Part 6. This section drafted in accordance with GB/T 1.1-2009 given rules. This section uses the redrafted law revision adopted ISO 13041-6.2009 "CNC lathe and turning center inspection conditions Part 6. Fine Precision machining test pieces. " This part of ISO 13041-6.2009 technical differences and the reasons are as follows. --- Normative references, this section with GB/T 16462.2-2017 and GB/T 16462.3-2017 instead ISO 13041-2 and ISO 13041-3, to adapt to China's technical conditions; --- International Standard 3.7 "The specimen materials, cutting tools and cutting parameters should be the agreement between suppliers/manufacturers and users", In this part of 3.7 to read "the specimen of the material, cutting tools and cutting parameters by the manufacturer custom" after the change is more reasonable; --- Removed the international standard 3.8 "Recommend the machine model and serial number, date of inspection and the location of the axis marked on the specimen, And the machine delivered at the same time for the user reference "clause, delete this article more in line with national conditions, because the specimen to be reused; --- International Standard 3.10 "Note 1, Note 2, Note 3 and Note 4" merged into "Note 1 and Note 2", the change is more reasonable; Change more reasonable; --- International Standard Table 5 b, i and m tolerance before the absence of "φ", this section adds "φ", the change is more reasonable; --- International Standard Table 5 m "in the hole N coaxial M to the outer hole" is wrong, this section is corrected as "the inner hole M of the outer hole N Concentricity". This section and ISO 13041-6.2009 there are technical differences, the provisions of these differences have been passed in the outer margin of the page margin The vertical single (|) is marked.

3 General requirements

3.1 measurement unit In this section, all linear dimensions, deviations and tolerances in millimeters (mm). All angle size units In terms of degrees, the units of angular deviation and corresponding tolerances are generally expressed as a ratio, but in some cases the values are also expressed in microseconds (μrad) or in angular seconds Said. The conversion is as follows. 0.010/1000 = 10μrad≈2 " 3.2 according to the standard Use this section should be in accordance with GB/T 17421.1, in particular, the installation of machine tools before testing, machine temperature rise, the description of test methods, testing Assessment and compensation of results. 3.3 inspection order The order of the inspection items listed in this section does not indicate the actual inspection sequence. In order to disassemble the inspection tools and inspection convenience, Italian order to test. ......
