GB/T 18400.7-2010Test conditions for machining centre -- Part 7: Accuracy of a finished test piece (English PDF)

Foreword

GB/T 18400 "Test conditions for machining centers" is divided into ten parts.

--- Part 1. horizontal spindle and with head Geometric tests for machines (horizontal Z-axis);

Universal spindle head Geometric tests for machines (vertical Z-axis) or vertical with vertical primary rotary axis;. --- Part 2

--- Part 3. with horizontal rotary axis of the main spindle head overall universal Geometric tests for machines (vertical Z-axis);

--- Part 4. positioning accuracy and linear and rotary axes repeatability test;

--- Part 5. Clamp the workpiece pallet positioning accuracy and repeatability of positioning accuracy test;

--- Part 6. feed rate, speed and accuracy test interpolation;

--- Part 7. finishing accuracy test specimen;

--- Part 8. Evaluation of the contouring performance in the three coordinate plane;

--- Part 9. Evaluation of conversion tool changer and pallet operation time;

--- Part 10. Evaluation of thermal effects.

This section GB/T 18400 Part 7.

This part identical with ISO 10791-7:1998 "Test conditions for machining centers - Part 7. Finishing accuracy test specimens" (English Chinese Version).

Taking into account China's national conditions, in the use of ISO 10791-7:1998 when this part has made several editorial changes.

--- "This standard" be replaced by "this section";

--- Title Chapter 3, "a brief description" to "General requirements";

--- Remove the ISO 10791-7:1998 Foreword and Introduction, increasing the national standards foreword;

--- Remove the ISO 10791-7:1998 Annex A (informative).

This part is proposed by China Machinery Industry Federation.

This part of the National Metal Cutting Machine Standardization Technical Committee (SAC/TC22) centralized.

This section is drafted. Beijing First Machine Tool Plant, Sichuan Changzheng Machine Tool Group Co., Ltd., Beijing Machine Tool Research Institute.

1 Scope

GB/T 18400 provisions of this part of the finishing conditions under standard test piece of a series of cutting inspection requirements, as well as the specimen itself Features and dimensions. This part can be used as cutting precision machining centers assessing the basic requirements. Under the agreement the supplier/manufacturer and users, it can be different and more rigorous test.

3 General requirements

4 Type, test pieces

It offers two types in this section, and each type has two specifications of the test piece. Type, size and marking specimens in Table 1.

In principle, at the time of acceptance of each specimen should be processed only one. In the case of special requirements, such as performance statistics assessed the machine, according to the system
