Full title and description

Test conditions for numerically controlled turning machines and turning centres — Part 4: Accuracy and repeatability of positioning of linear and rotary axes (ISO 13041-4:2004). This part specifies the tolerances that apply to the positioning tests for linear axes (up to 2 000 mm) and rotary axes of NC turning machines and turning centres.

Abstract

ISO 13041-4:2004, referring to ISO 230-2, defines the accuracy and repeatability requirements and the tolerances to be used when performing positioning tests on the linear and rotary axes of numerically controlled turning machines and turning centres. It limits its scope to positioning tolerances (linear axes up to 2 000 mm and rotary axes) and explicitly does not address environmental conditions, machine warm-up or measuring methods already covered in ISO 230-2.

Scope

This part of ISO 13041 specifies tolerances applicable to positioning tests for linear axes (up to 2 000 mm stroke) and rotary axes of numerically controlled turning machines and turning centres. It is intended for verification of positioning accuracy and repeatability, and does not cover environmental conditioning, machine warm-up procedures or measurement methods already described in ISO 230-2.

Key topics and requirements

• Defined tolerances for positioning tests of linear axes (up to 2 000 mm) and rotary axes.
• Focus on accuracy and repeatability (positioning error and repeatability metrics) for NC turning machines and turning centres.
• Reference and dependence on ISO 230-2 for measurement methods and broader test code context.
• Applicability to type testing, acceptance testing and comparative verification where positioning performance is evaluated.
• Concise, prescriptive tolerancing (short, 6-page technical part intended to be used alongside other ISO 13041 parts).

Typical use and users

Used by machine-tool manufacturers, test laboratories, quality/inspection engineers, machine acceptance teams and purchasing/specification engineers who need to verify or specify the positioning accuracy and repeatability of NC turning machines and turning centres. It is used alongside other ISO 13041 parts and ISO 230 series documents when performing formal geometric and positioning tests.

Related standards

ISO 13041-4 is part of the ISO 13041 series (geometric and test conditions for NC turning machines). Relevant related standards include ISO 13041-1 (geometric tests for machines with horizontal workholding spindles), ISO 13041-2 (geometric tests for machines with vertical workholding spindle) and ISO 13041-3 (geometric tests for machines with inverted vertical workholding spindles). ISO 13041-4 explicitly refers to the ISO 230 series for measurement methods, most directly ISO 230-2 for positioning test methodology.

FAQ

Q: What is this standard?

A: ISO 13041-4:2004 is the part of the ISO 13041 series that specifies tolerances and requirements for accuracy and repeatability of positioning of linear and rotary axes on numerically controlled turning machines and turning centres.

Q: What does it cover?

A: It covers the tolerances to be applied when carrying out positioning tests on linear axes (up to 2 000 mm) and rotary axes, and is used for verifying positioning accuracy and repeatability. It does not cover environmental conditions, warm-up procedures or measurement techniques already addressed in ISO 230-2.

Q: Who typically uses it?

A: Machine-tool manufacturers, metrology and test laboratories, QA/inspection engineers, acceptance test teams and procurement/specification engineers who must verify or specify NC turning-machine positioning performance.

Q: Is it current or superseded?

A: ISO 13041-4 was published in 2004 (Edition 1) and, according to ISO's lifecycle information, the publication has been subject to periodic systematic review and was confirmed as the current version in ISO's review cycle (confirmation entries in 2013, 2019 and 2024). Users should check ISO or their national standards body for the latest confirmation or revision status before formal use.

Q: Is it part of a series?

A: Yes — ISO 13041 is a multi-part series addressing test conditions for NC turning machines and turning centres (for example, Parts 1, 2 and 3 cover geometric tests for different spindle configurations). ISO 13041-4 is the part dealing specifically with positioning accuracy and repeatability for linear and rotary axes.

Q: What are the key keywords?

A: Positioning accuracy; repeatability; linear axes; rotary axes; NC turning machines; turning centres; tolerances; ISO 230-2; geometric tests.
