GB/T 18400.9-2007Test conditions for machining centre -- Part 9: Evaluation of the operating times of tool change and pallet change (English PDF)

Foreword

GB/T 18400 "Test conditions for machining centers" is divided into 11 parts.

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

--- Part 2. Vertical or universal machines with vertical spindle heads (vertical Z-axis) Geometric tests;

--- Part 3. universal spindle head is fixed indexing or continuous indexing machine (vertical Z-axis) Geometric tests;

--- 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 interpolation accuracy test;

--- Part 7. finishing accuracy test specimen;

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

--- Part 9. Evaluation of tool change and pallet exchange operation time;

--- Part 10. Evaluation of thermal effects;

--- Part 11. Evaluation of noise emission.

This section GB/T Part of 918,400.

This part identical with ISO 10791-9:2001 "Test conditions for machining centers - Part 9. tool change and pallet exchange operation time Evaluation "(in English).

For ease of use, this section made the following editorial changes.

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

"." --- With a decimal point instead of a comma as the decimal point, "";

--- Canceled the foreword and introduction of international standards.

Appendix A of this section is an informative annex.

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 Machine Tool Research Institute.

1 Scope

This section GB/T 18400 specifies the processing center (hereinafter referred to as the machine) under standard test conditions established by the implementation of different metals Normal operation evaluation method of cutting the time required for the function.

This section applies to assess the following two functions operating time.

--- Automatic tool exchange (see Chapter 5);

--- Automatic pallet exchange (see Chapter 6).

Comparison between GB/T 18400, the method in this section are applicable to different specifications and features similar to the machine performance.

Data and unified way to compare the obtained also apply to the establishment of the technical report regular exchange time, as well as in new machines and During the inspection tool life.

3 Terms and Definitions

A knife from the reference position PR processing zones started switching to the next position until the knife reaches the same interval.

NOTE. determining automatic tool exchange operation, CTC is more suitable than a simple tool change time, because CTC consider all the steps required for automatic tool exchange.

A pallet from the reference position PR processing zones started switching to the next pallet to reach the same position until the interval.
