IS 15635 : Part 3 : 2006 /ISO 10360-3 : 2000 Geometrical Product Specifications (GPS) - Acceptance and Reverification Tests for Coordinate Measuring Machines (CMM) - Part 3 : CMMs with the AXIS of a Rotary Table as the Fourth AXIS

National Foreword

This Indian Standard (Part 3) which is identical with ISO 10360-3 : 2000 ?Geometrical ProductSpecifications (GPS) - Acceptance and reverification tests for coordinate measuring machines(CMM) - Part 3 : CMMs with the axis of a rotary table as the fourth axis? issued by the InternationalOrganization for Standardization (ISO) was adopted by the Bureau of Indian Standards on therecommendation of the Engineering Metrology Sectional Committee and approval of the MedicalInstruments, General and Production Engineering Division Council.

Coordinate measuring machines (CMMs) are most modern method of dimensional inspection. with theadvent of numerically controlled machine tools, demand grew for a means to support this equipmentwith faster first piece inspection and in many cases 100 percent inspection. To fill this gap CMMs weredeveloped by modifying precision layout machines.

The acceptance test and reverification test of this part of ISO 10360 are applicable to CMMs which usea rotary table for the orientation of a workpiece being measured.

The tests specified in this part of ISO 10360 are performed in addition to the size measuring testsaccording to ISO 10360-2, which are conducted with the rotary table stationary. They are designed todetect the system measuring errors relative to an axis system fixed to the rotary table. It is normally notuseful to isolate the rotary table errors from other sources of machine error.

The text of the ISO Standard has been approved as suitable for publication as an Indian Standardwithout deviations. Certain terminology and conventions are, however, not identical to those used inIndian Standards. Attention is particularly drawn to the following:

a) Wherever the words ?International Standard? appear referring to this standard, they shouldbe read as ?Indian Standard?.

b) Comma (,) has been used as a decimal marker in the International Standard, while in IndianStandards, the current practice is to use a point (.) as the decimal marker.

In this adopted standard, reference appears to certain International Standards for which Indian Standardsalso exist. The corresponding Indian Standards which are to be substituted in their places are listedbelow along with their degree of equivalence for the editions indicated:
