4 Doc No.: PGD 35 (12788) IS/ISO : 2015 Machine Tools, Machine Tool Elements and Holding Devices Sectional Committee, PGD 35 NATIONAL FOREWORD This Indian Standard (Part 5) (First Revision) which is identical with ISO : 2015 Test conditions for numerically controlled turning machines and turning centres Part 5: Accuracy of speeds and interpolations issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Cutting Tools Sectional Committee and approval of the Production and General Engineering Division Council. This standard was originally published in 2016 by adopting ISO : 2006 Test conditions for numerically controlled turning machines and turning centres Part 5: Accuracy of speeds and interpolations. The first revision of this standard has been undertaken to align it with the latest version of ISO : The major changes in this revision are as follows: The tolerances in tests AK5, BK5, and CK5, which are reduced from ISO (Test K5) due to improved centring procedure or practical experience that proves that the closer tolerances can be met. References have been updated. Other parts in this series are: Part 1 Part 2 Part 3 Part 4 Part 6 Part 7 Part 8 General survey, correlation and determination of dimensions Geometric tests for machines with a vertical workholding spindle Geometric tests for machines with inverted vertical workholding spindles Accuracy and repeatability of positioning of linear and rotary axes Accuracy of a finished test piece Evaluation of contouring performance in the coordinate planes Evaluation of thermal distortions The text of ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminology and conventions are, however, not identical to those used in Indian Standards: attention is particularly drawn to the following: a) Wherever the words International Standard appear, referring to this standard, they should be read as Indian Standard. b) Comma (, ) has been used as a decimal marker while in Indian Standards 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 Standards also exist. The corresponding Indian Standards, which are to be substituted in their respective places, are listed below along with their degree of equivalence for the editions indicated:

5 International Standard Corresponding Indian Standard Degree of Equivalence ISO Test code for machine tools Part 1: Geometric accuracy of machines operating under no-loador quasi-static conditions ISO Test code for machine tools Part 4: Circular tests for numerically controlled machine tools ISO Test conditions for numerically controlled turning machines and turning centres Part 1 : Geometric tests for machines with a horizontal workholding spindle ISO Test conditions for numerically controlled turning machines and turning centres Part 2: Geometric tests for machines with a vertical workholding spindle ISO Test conditions for numerically controlled turning machines and turning centres Part 3: Geometric tests for machines with inverted vertical workholding spindles IS : 2016 Test Code for Machine Tools - Part 1 : Geometric Accuracy of Machines Operating Under No-load or Finishing Conditions (Second Revision) IS : 2016 Test code for machine tools Part 4 Circular tests for numerically controlled machine tools IS : 2004 Test Conditions for Numericallly Controled Turning Machines and Turning Centres Part 1 Geometric Tests for Machines with a Horizontal Workholding Spindle IS : 2008 Test Conditions for Numerically Controlled Turning Machines and Turning Centres Part 2 Geometric Tests for Machines with a Vertical Workholding Spindle IS : 2009 Test Conditions for Numerically Controlled Turning Machines and Turning Centres Part 2 Geometric Tests for Machines with a Vertical Workholding Spindle ISO : 2012 ISO : 2005 ISO : 2004 ISO : 2008 ISO : 2009 The technical committee has reviewed the provisions of the following International Standards referred in this adopted standard and has decided that they are acceptable for use in conjunction with this standard: International Standard ISO 841 Title Industrial automation systems and integration Numerical control of machines Coordinate system and motion nomenclature

6 ISO Machine tools Numerical compensation of geometric errors For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated expressing the result of a test or analysis, shall be rounded off in accordance with IS 2 : 1960 Rules for rounding off numerical values (revised). The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard. For 4 th cover page: Doc. No.: PGD 35 (12788)
