Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

This standard replaces GB/T 16461-1996 "single point turning tool life test." this standard compared with GB/T 16461-1996, in addition to editorial changes outside the main technical differences are as follows.

--- Remove the ISO foreword;

--- Remove the foreword statement Appendix nature, increasing the draft rules are based on standards for the preparation, increasing the technical differences correspond to international standards;

--- Revised introduction;

--- Modify the list of normative references;

--- Modify the terms of the narrative;

--- Remove the body of the statement of the nature of the Appendix;

Appendix B Table B.1 --- the content of "S" from "0.02 to 0.035" to "maximum 0.035";

--- Remove Appendix F F.1 "Overview";

--- References section instead of using the applicable country file.

This standard uses redrafted law revision using ISO 3685:1993 "single point turning tool life test." this standard and ISO 3685:1993 is the main technical difference.

Introduction

This standard covers can be used for single-point turning tool laboratories and manufacturing units recommended life testing. When the cutting tool, workpiece material, cutting fluid or cutting parameters were compared, these recommendations aimed at harmonizing steps to improve the reliability and comparability of test results. As close as possible to these objectives, including the recommended reference material standards, can be employed both as far as practicable.

In addition, the standard recommended values may be used to help determine the recommended cutting data or determine the value of constraints and processing characteristics, such as cutting force, the machined surface characteristic values and the like in the form of chips. For these purposes, even though the already recommended values were given certain parameters, it may be used as a variable.

The recommended standard test conditions intended to be used on steel and cast iron specimen with normal microstructure for turning test the overall high-speed steel cutting tools, carbide or ceramic tools. However, this standard may be appropriate modifications, for example, it is used for other workpiece material or special tools developed for turning test.

The accuracy of the recommended values specified shall be considered as a minimum requirement. Any deviation from the recommended values should be described in detail in the test report.

Single point turning tool life test

1 Scope

This standard specifies the use of high speed steel, carbide ceramics and life testing single point turning tool turning steel and cast iron recommended procedure. Regulate the following factors involved in the test. the workpiece, tool, cutting fluids, cutting conditions, equipment, tool life and tool failure assessment, test procedure and recording, evaluation and reporting of results. This standard does not specify acceptance tests.

In the turning test to consider cutting conditions using the following two types.

a) mainly due to wear and failure conditions, it is the condition of this standard the main consideration;

b) due to other phenomena, such as cracking or plastic deformation of the cutting edge and the failure condition, this condition requires further study.

This standard applies to real life test laboratory and production of single point turning tool, see Appendix A.
