GB/T 18400.5-2010Test conditions for machining centre -- Part 5: Accuracy and repeatability of positioning of work-holding pallets (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 5.

This part identical with ISO 10791-5:1998 "Test conditions for machining centers - Part 5. Positioning precision workpiece clamping and heavy pallets Re-positioning accuracy test "(in English).

Taking into account China's national conditions, in the use of ISO 10791-5:1998 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 10791-5:1998 Foreword and Introduction, increasing the national standards foreword;

--- Remove the ISO 10791-5:1998 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.

1 Scope

This section GB/T 18400 specifies the respective workpiece holding pallet on the machine (hereinafter referred to as the pallet) repeat positioning accuracy and a set of care Plate positioning accuracy of testing methods and tolerances.

This section applies to a single processing center with multiple pallet does not apply to the processing center manufacturing systems. In Manufacturing Systems, Engineering Positioning accuracy member or workpiece holding fixture depends on cooperation with the pallet receiving means. Only when the test tool is placed in a different location of the machine with respect to the origin of the linear axis is exactly the same, this part of the test results can be extended to the entire manufacturing system. In fact it is difficult to Do, and there is an error, because the origin of the linear axis impact repeatability axis by.
