Full title and description

St ISO 13041-5-2015 — Test conditions for numerically controlled turning machines and turning centres — Part 5: Accuracy of speeds and interpolations. This part specifies kinematic tests for NC turning machines and turning centres addressing spindle speeds, linear-axis feed speeds and the accuracy of interpolated paths produced by simultaneous motion of two or more axes.

Abstract

ISO 13041-5:2015 defines test procedures (with references to ISO 230-1 and ISO 230-4) to assess spindle speed accuracy, feed-speed accuracy of individual NC linear axes, and the accuracy of paths generated by simultaneous linear and/or rotary axis interpolations for numerically controlled turning machines and turning centres (horizontal, vertical and inverted vertical workholding spindles).

Scope

This part of ISO 13041 specifies kinematic test conditions and acceptance checks for numerically controlled turning machines and turning centres. Tests cover spindle-speed measurement and deviation, linear-axis feed-speed checks at defined feed rates (including maximum speed), and contouring/interpolation accuracy (radial deviation for circular interpolation, contouring in coordinate planes). Methods reference measuring devices and procedures from ISO 230 (for example, interferometers, telescopic ball bars, revolution counters/stroboscopes) and define typical test diameters, feed rates and tolerance categories for general-purpose and normal-accuracy machines.

Key topics and requirements

• Spindle speed accuracy tests (instantaneous and averaged readings; use of stroboscope or revolution counters; deviation expressed as percentage of programmed speed).
• Linear-axis feed-speed verification at specified test speeds (e.g., 1 000 mm/min and maximum speed), accounting for acceleration/deceleration effects.
• Contour/interpolation accuracy tests including circular interpolation radial deviation over specified angles and diameters (XY, YZ, ZX planes and other axis pairs).
• Use of measuring equipment: interferometer, telescopic ball bar, special fixtures, laser heads and reflectors as appropriate for each test.
• Reference to ISO 230‑1 and ISO 230‑4 test methods and acceptance criteria; tolerances given for typical test objects (examples: AK5, BK2 and CK5 test arrangements).
• Guidance for performing tests to support comparison, acceptance, maintenance and verification of NC turning machines and turning centres.

Typical use and users

Applied by machine-tool manufacturers, acceptance and commissioning engineers, independent test laboratories, quality assurance and metrology teams, procurement/specification authors, and research groups assessing performance of NC turning machines and turning centres. Common uses include factory acceptance tests, periodic verification, troubleshooting, machine commissioning, and specification compliance checks.

Related standards

ISO 13041-5 is part of the ISO 13041 series (parts 1–8 covering geometric tests, positioning, finished test pieces, contouring performance and thermal effects). It is used together with ISO 230 series methods (notably ISO 230-1 and ISO 230-4) for measurement procedures and reference test definitions. The document was prepared under ISO/TC 39 (Machine tools), subcommittee SC 2 (test conditions for metal cutting machine tools).
