Full title and description

ISO 10791-6:2014 — Test conditions for machining centres — Part 6: Accuracy of speeds and interpolations. This international standard specifies kinematic test methods for machining centres to verify spindle speeds, feeds and the accuracy of interpolated paths generated by simultaneous movement of two or more numerically controlled linear and/or rotary axes.

Abstract

Specifies, with reference to ISO 230‑1 and ISO 230‑4, kinematic tests for machining centres concerning spindle speeds, feed rates and the accuracy of paths described by simultaneous movement of NC linear and/or rotary axes. Applies primarily to machines with three linear axes (X, Y, Z) and one or two rotary axes (A, B or C); tests for other movements are treated as special features and are not included. The standard is intended for verification of kinematic accuracy and does not cover machine dynamic behaviour such as vibration or noise.

Scope

Applies to machining centres with three linear axes (X, Y, Z) up to typical travel ranges and additionally one or two rotary axes (A, B or C). Defines kinematic verification tests for spindle speed accuracy, feed (axis speed) verification and the geometric accuracy of interpolated motions (including circular interpolation and multi‑axis interpolations). The part addresses only kinematic accuracy (positioning and path accuracy under commanded motion) and excludes operational checks such as vibration, abnormal noise, thermal effects (covered in other parts), or special machine motions unless specifically agreed between supplier and user.

Key topics and requirements

• Defined kinematic test procedures for spindle speed accuracy across ranges and directions (CW/CCW).
• Feed-rate verification for individual NC linear axes and checks at typical and maximum feed conditions.
• Accuracy of interpolations: tests for circular interpolation and simultaneous multi‑axis path generation, with methods for measuring path deviation and radial/runout errors.
• Procedures for 4‑ and 5‑axis (rotary axis) configurations and associated annexes for more complex centre geometries.
• Reference to measurement and test principles in ISO 230‑1 and ISO 230‑4; test reporting and acceptance criteria intended to support commissioning, acceptance testing and comparative evaluation.
• Provisions for partial application of tests by agreement between manufacturer/supplier and user (special features may be excluded).

These topics and the typical test structure are described in the standard text and accompanying annexes.

Typical use and users

Used for factory acceptance testing (FAT), site acceptance testing (SAT) and periodic verification of numerically controlled machining centres by machine manufacturers, end‑users (manufacturing engineering and QA), metrology providers and test labs. Also used by tooling and process engineers who need objective measures of interpolated path accuracy when qualifying machines for high‑precision multi‑axis machining.

FAQ

Q: What is this standard?

A: ISO 10791-6:2014 is an international standard that defines kinematic test methods to verify the accuracy of speeds, feeds and interpolated motion on numerically controlled machining centres.

Q: What does it cover?

A: It covers spindle speed accuracy, feed (axis speed) verification and the accuracy of paths described by simultaneous movement of two or more linear and/or rotary NC axes (including circular and multi‑axis interpolations). It does not cover dynamic or operational issues like vibration or thermal distortion (those are treated in other parts of the ISO 10791 series).

Q: Who typically uses it?

A: Machine tool manufacturers, metrology/test laboratories, quality and inspection engineers, and end‑users requiring objective acceptance and verification procedures for CNC machining centres.

Q: Is it current or superseded?

A: The 1998 edition (ISO 10791‑6:1998) was withdrawn and replaced by ISO 10791‑6:2014 (Edition 2). The 2014 edition is the current published version.

Q: Is it part of a series?

A: Yes — ISO 10791 is a multi‑part series covering test conditions for machining centres (Parts 1–10 cover geometric tests, positioning, interpolations, finished test pieces, contouring performance, operating times, thermal distortion, etc.). ISO 10791‑6 specifically addresses speeds and interpolations.

Q: What are the key keywords?

A: CNC machining centre, interpolation accuracy, spindle speed, feed verification, kinematic tests, ISO 230, multi‑axis machining.
