Full title and description

Test conditions for machining centres — Part 10: Evaluation of thermal distortions. This International Standard specifies test methods and conditions for evaluating thermal distortions of machining-centre structures and positioning systems (vertical and horizontal spindle machines) to assess how temperature and machine operation affect geometric accuracy and relative positioning between tool and workpiece.

Abstract

This document defines four standardized tests for the evaluation of thermal distortions: environmental temperature variation error; thermal distortion caused by a rotating spindle; thermal distortion caused by moving linear axes; and thermal distortion caused by rotary motion of components. It applies to machining centres with numerically controlled linear axes (examples of maximum axis lengths are given for X, Y and Z depending on spindle orientation) and is intended to be used in conjunction with ISO 230‑3.

Scope

The standard specifies test procedures for evaluating thermal distortions of machining-centre machine tool structures and their positioning systems. It covers vertical-spindle machines with numerically controlled linear axes up to 5 000 mm (X) and up to 2 000 mm (Y and Z), and horizontal-spindle machines with specified maximum axis lengths (for example X up to 5 000 mm, Y up to 3 200 mm, Z up to 2 000 mm). The tests are intended to characterise machine behaviour under ambient temperature change and under thermal load generated by spindle rotation, linear-axis motion and rotary components; results are reported to support comparison, acceptance, maintenance and performance verification (used together with ISO 230‑3).

Key topics and requirements

• Four defined thermal tests: environmental temperature variation error; thermal distortion from a rotating spindle; thermal distortion from moving linear axes; thermal distortion from rotary motion of components.
• Requirements for measurement instrumentation, sensor placement and recording of ambient and machine temperatures, and for reporting numerical and graphical results.
• Procedures for machine thermal equilibration, test sequencing and data presentation; tests may be run individually or combined and results must document test setup, spindle speeds, sensor locations and any compensation applied.
• Guidance that numerical acceptance criteria are not fixed by the standard and should be agreed between supplier and user (the standard provides test methods and reporting requirements rather than prescriptive tolerances).
• Intended interoperability with ISO 230‑3 (Test code for machine tools — determination of thermal effects).

Typical use and users

Used by machine‑tool manufacturers, machine-shop quality and testing engineers, independent test laboratories, procurement and acceptance teams, and researchers. Typical uses include factory acceptance testing, post‑installation verification, troubleshooting of thermal error sources, benchmarking between machine designs, and qualification for production where thermal stability affects part accuracy.

Related standards

Q: What is this standard?

A: ISO 10791‑10:2022 is an ISO International Standard that specifies test conditions and methods for evaluating thermal distortions of machining centres (machine tool structure and positioning system).

Q: What does it cover?

A: It covers four thermal tests (environmental temperature variation error; spindle‑rotation thermal distortion; moving linear‑axis thermal distortion; and rotary‑component thermal distortion), measurement and reporting requirements, sensor and test‑setup guidance, and is intended to be used with ISO 230‑3.

Q: Who typically uses it?

A: Machine‑tool OEMs, validation and quality engineers, test labs, purchasing/acceptance teams and researchers concerned with machine thermal behaviour and part‑accuracy assurance.
