Full title and description

St ISO 10791-9:2001 — Test conditions for machining centres — Part 9: Evaluation of the operating times of tool change and pallet change. This part defines standard test conditions and measurement methods for determining the operating times of automatic tool-change and automatic pallet-change functions on machining centres, to allow objective comparison of machine performance and to establish conventional change-time data for technical literature and acceptance testing.

Abstract

This standard specifies procedures for measuring and reporting the durations of two principal change operations on machining centres: automatic tool change and automatic pallet change. It describes test setups, defined sequences, measurement points and reporting formats so that results from different machines (of comparable size and features) can be compared consistently. The data are intended for use by manufacturers, test laboratories, purchasers and standards developers to characterise and document changeover performance.

General information

• Status: Published (International Standard; confirmed).
• Publication date: 15 March 2001 (Edition 1).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 25.040.10 — Machining centres.
• Edition / version: Edition 1 (2001).
• Number of pages: 15 (ISO edition).

Scope

Applies to machining centres equipped with automatic tool-change and/or automatic pallet-change systems. The standard defines how to measure changeover operating times under specified, repeatable test conditions so as to permit objective performance comparison between similar machines, both at acceptance and during the machine life cycle. It does not address safety requirements or detailed functional design of changers; it is focused on test methods and reporting of measured times.

Key topics and requirements

• Definition of operating-time categories for automatic tool change (e.g., magazine access, arm movement, spindle coupling/uncoupling).
• Definition of operating-time categories for automatic pallet change (e.g., pallet removal, transfer, clamping/unclamping).
• Specified test sequences and repeatability procedures to obtain representative timing data.
• Measurement points, timing start/stop criteria and instrumentation recommendations.
• Environmental and machine-condition prerequisites (e.g., no-load conditions, tool/pallet configurations).
• Reporting formats and data to be recorded to support comparison (mean times, number of cycles, observed variances).
• Limitations and guidance on applicability (comparability only for machines of similar size/configuration).

Typical use and users

Used by machine-tool manufacturers for product specification and validation, by test laboratories and certification bodies for performance evaluation, by procurement/purchasing professionals to compare vendors, and by research groups studying automation and cycle-time optimisation in CNC machining environments.

FAQ

Q: What is this standard?

A: ISO 10791-9:2001 is Part 9 of the ISO 10791 series; it provides standardized test methods to evaluate the operating times of tool-change and pallet-change functions on machining centres.

Q: What does it cover?

A: It covers definitions, test setups, timing criteria and reporting formats to measure automatic tool-change and automatic pallet-change times under repeatable conditions so results are comparable across similar machines. It does not cover safety design requirements or full machine acceptance tests beyond the timing aspects.

Q: Who typically uses it?

A: Machine manufacturers, independent test laboratories, purchasers and quality/acceptance engineers, as well as researchers focused on cycle-time and automation performance.

Q: Is it current or superseded?

A: The ISO bibliographic record shows ISO 10791-9:2001 as the published edition (2001) and it has been subject to periodic review; the ISO record indicates it was confirmed as current in the systematic review cycle (most recently reviewed/confirmed by ISO). Users should check the national or ISO catalogue for any later amendments or replacements before relying on the text for regulatory or contractual purposes.

Q: Is it part of a series?

A: Yes — ISO 10791 is a multipart standard (Parts 1 through at least 12) that together define a broad set of test conditions for machining centres, covering geometric tests, axis accuracy, contouring performance, finished-piece accuracy, thermal effects, noise and vibration, and other performance characteristics.

Q: What are the key keywords?

A: Machining centre, tool change, pallet change, operating time, test conditions, automatic tool changer, automatic pallet changer, ISO 10791.
