Full title and description

St ISO 10791-5-1998 — Test conditions for machining centres — Part 5: Accuracy and repeatability of positioning of work‑holding pallets. This part of ISO 10791 specifies test methods and criteria for assessing the positioning accuracy and repeatability of pallets and pallet receivers used on single machining centres with multiple pallets.

Abstract

ISO 10791-5:1998 defines the test arrangements, measurement procedures, formulae and tolerances needed to evaluate (a) the repeatability of locating individual pallets on a machine and (b) the positioning accuracy of a batch of pallets relative to a pallet receiver. The tests are given with reference to ISO 230‑1 and ISO 230‑2 measurement practices and focus on the mechanical fit and resulting positional errors between pallets and the receiver on a single machining centre.

Scope

This part of ISO 10791 applies to a single machining centre equipped with a single pallet receiver that accepts multiple pallets. It defines the tests for: (1) repeatability of positioning of individual pallets (i.e., ability to return a pallet to the same location), and (2) overall positioning accuracy of a batch of pallets relative to the pallet receiver. The standard references ISO 230‑1 and ISO 230‑2 for measurement units and ambient/test conditions and limits its scope to the machine‑level assessment (it does not attempt to characterise a whole production line unless identical measuring arrangements on each machine are used).

Key topics and requirements

• Definitions and preliminary remarks (measurement units, axis coding, references to ISO 230‑1/230‑2).
• Measurement instruments and their placement for pallet repeatability tests.
• Procedures and formulae for calculating deviations from individual readings and for batch positioning errors.
• Specified tolerances and acceptance criteria for repeatability and positioning accuracy of pallets.
• Requirements for documenting test conditions and results so that comparisons between machines or manufacturers are reproducible.
• Notes on limitations: applies to single receiver machines; extension to whole‑system accuracy requires careful, identical measurement setup on each machine.

Typical use and users

Used by machine‑tool manufacturers, quality and metrology laboratories, acceptance and test engineers, production engineers specifying machine procurement, and purchasing agents who require objective, comparable performance data for palletised machining centres. Test houses and certification bodies also apply these procedures during machine acceptance and factory inspection.

Related standards

ISO 10791 is a multi‑part series; related parts include ISO 10791‑1 (geometric tests for certain horizontal‑spindle machines), ISO 10791‑3 (geometric tests for machines with universal heads), ISO 10791‑4 (accuracy and repeatability of linear and rotary axes) and other parts addressing different machine configurations. ISO 10791‑5 explicitly references ISO 230‑1 and ISO 230‑2 (test code for machine tools) for measurement principles and environmental/test condition guidance.

FAQ

Q: What is this standard?

A: ISO 10791‑5:1998 is an ISO international standard that defines test conditions and measurement procedures to assess the accuracy and repeatability of positioning for work‑holding pallets on machining centres (single receiver with multiple pallets).

Q: What does it cover?

A: It covers the measurement setups, instruments, procedural steps, calculation formulae and tolerances needed to evaluate pallet repeatability (individual pallet relocation) and the positioning accuracy of a batch of pallets relative to the pallet receiver; references ISO 230‑1 and ISO 230‑2 for measurement practice.

Q: Who typically uses it?

A: Machine‑tool manufacturers, acceptance/test engineers, metrology and calibration laboratories, production engineers, and procurement professionals who need standardised methods to compare palletised machining centre performance.

Q: Is it current or superseded?

A: The ISO metadata lists ISO 10791‑5 as the 1998 edition and indicates periodic confirmation/review activity; consult the ISO catalogue or a national standards body for the most current confirmation or revision status for your country before purchase or formal citation.

Q: Is it part of a series?

A: Yes — ISO 10791 is a multipart series covering test conditions for different machining‑centre geometries and performance aspects (geometric tests, axis positioning, pallet systems, etc.). ISO 10791‑5 is the pallet‑related part of that series.

Q: What are the key keywords?

A: Machining centres, pallet receiver, pallet repeatability, positioning accuracy, ISO 10791, ISO 230, test conditions, machine acceptance, metrology.
