IS 15635 : Part 1 : 2006 /ISO 10360-1 : 2000 Geometrical Product Specifications (GPS) - Acceptance and Reverification Tests for Coordinate Measuring Machines (CMM) - Part 1 : Vocabulary

National Foreword

This Indian Standard (Part 1) which is identical with ISO 10360-1 :2000 ?Geometrical ProductSpecifications (GPS) - Acceptance and reverification tests for ?coordinate measuring machines(CMM) - Part 1 : Vocabulary? issued by the International Organization for Standardization (ISO) wasadopted by the Bureau of Indian Standards on the recommendation of the Engineering MetrologySectional Committee and approval of the Medical Instruments, General and Production EngineeringDivision 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 text of this 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 while in Indian Standards, the current practiceis to use a point (.) as the decimal marker.

ISO 10360 consists of the following other parts:

Part 2 CMMs used for measuring size

Part 3 CMMs with the axis of a rotary table as the fourth axis

Part 4 CMMs used in scanning measuring mode

Part 5 CMMs using multiple-stylus probing systems

Part 6 Estimation of errors in computing Gaussian associated features

Technical Corrigendum 1 to the above International Standard has been given at the end of thispublication.

For the purpose of deciding whether a particular requirement of this standard is complied with, the finalvalue, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordancewith IS 2 : 1960 ?Rules for rourtding off numerical values (revised)?. The number of significant placesretained in the rounded off value should be the same as that of the specified value in this standard.
