Full title and description

Test conditions for numerically controlled turning machines and turning centres — Part 7: Evaluation of contouring performance in the coordinate planes. This International Standard specifies circular test procedures and evaluation metrics (radial deviation F and circular deviation G) for assessing contouring/interpolation performance of NC turning machines and turning centres in their coordinate planes.

Abstract

ISO 13041-7:2004 describes a method of checking the contouring performance of turning centres (numerically controlled turning) by conducting circular tests and evaluating radial deviation F and circular deviation G in accordance with the principles of ISO 230-4:1996. The tests verify circular movement at one position per coordinate plane, at a single feed rate, and repeated in the opposite contouring direction.

Scope

Specifies test conditions and evaluation procedures for the assessment of contouring (interpolative) performance of NC turning machines and turning centres in the coordinate planes. The standard defines circular test patterns, measurement positions and the calculation of radial and circular deviations to characterise the ability of the control and drive system to follow commanded circular contours. It is intended for machines up to the range covered by the ISO 13041 series and references measurement principles in ISO 230-4:1996.

Key topics and requirements

• Definition of circular test procedures to assess contouring/interpolation accuracy in coordinate planes.
• Evaluation metrics: radial deviation F and circular deviation G (as referenced to ISO 230-4 methodologies).
• Test conditions: single feed rate, one verification position per coordinate plane, repeat test in opposite contour direction.
• Instrumentation and measurement considerations consistent with ISO 230 series practices.
• Reporting of results to allow comparison between machines and verification against manufacturer specifications.

Typical use and users

Used by machine tool manufacturers, quality engineers, metrology specialists, test laboratories and end users (workshops, production engineering) to verify and document the contouring performance of NC turning machines and turning centres during acceptance testing, periodic verification and comparative evaluations.

FAQ

Q: What is this standard?

A: ISO 13041-7:2004 is Part 7 of the ISO 13041 series that specifies test conditions and evaluation methods for the contouring performance of numerically controlled turning machines and turning centres.

Q: What does it cover?

A: It covers circular test procedures in the machine coordinate planes and defines evaluation of radial deviation (F) and circular deviation (G) to characterise the machine's ability to follow circular contours, with tests performed at one feed rate and repeated in the opposite direction.

Q: Who typically uses it?

A: Machine tool manufacturers, test laboratories, metrology engineers, quality assurance teams and end users conducting acceptance, verification or comparative performance testing of NC turning machines.

Q: Is it current or superseded?

A: The document is the 2004 edition and has been subject to periodic ISO confirmation reviews; as of the last systematic review it remains the current 2004 edition. Users should check with their national standards body or ISO for the absolute latest status before relying on it for regulatory or procurement requirements.

Q: Is it part of a series?

A: Yes — it is one part of the ISO 13041 series (test conditions for numerically controlled turning machines and turning centres) and is intended to be used together with other parts in that series and with relevant ISO 230 test-method standards.

Q: What are the key keywords?

A: Contouring performance, circular test, radial deviation F, circular deviation G, NC turning, turning centres, interpolation accuracy, ISO 230-4.
