ISO 10791-1-2015 PDF

Full title and description

Test conditions for machining centres — Part 1: Geometric tests for machines with horizontal spindle (horizontal Z‑axis). This part of ISO 10791 specifies geometric test procedures and acceptance checks (with reference to ISO 230) for three‑axis numerically controlled machining centres having a horizontal spindle, including provisions for several table and rotary/tilting table configurations.

Abstract

ISO 10791-1:2015 defines the geometric tests used to verify positioning and geometric accuracy of machining centres with a horizontal spindle (horizontal Z‑axis). It applies primarily to three linear NC axes (X, Y, Z) and covers common table types and supplementary rotary/tilting movements; accessory spindle heads are excluded (covered by ISO 17543‑1). The standard focuses on geometric accuracy verification and references ISO 230 test codes for measurement principles.

Scope

Specifies geometric test methods for machining centres with horizontal spindle (horizontal Z‑axis). It applies to machining centres with three numerically controlled linear axes (typical dimensional limits given in the standard: X up to 5 000 mm, Y up to 3 200 mm, Z up to 2 000 mm), and it describes tests for a range of table types (fixed, rotary around vertical or horizontal axes, tilting). The part deals only with geometric accuracy verification — operational and non‑geometric tests are covered in other parts of ISO 10791 and by ISO 230 series test codes. Accessory spindle heads are outside the scope of this part (see ISO 17543‑1).

Key topics and requirements

• Definitions and test conditions for geometric verification of horizontal‑spindle machining centres.
• Detailed procedures for measuring positioning, straightness, squareness and angular errors of linear and rotary elements.
• Application limits for axis travel (X ≤ 5 000 mm, Y ≤ 3 200 mm, Z ≤ 2 000 mm) and treatment of supplementary rotary/tilting tables.
• Reference to ISO 230 measurement methods and tolerancing principles for machine tool testing.
• Exclusion of accessory spindle heads (refer to ISO 17543‑1) and emphasis on geometric (not operational) testing.
• Annexes addressing common table configurations (four table types) and informative material on test set‑ups and interpretation.

Typical use and users

Used by machine tool manufacturers (for factory acceptance and specification), test and calibration laboratories, quality and metrology engineers, machine purchasers and acceptance teams, OEM service organizations, and research groups assessing machine geometric performance. The standard is applied during acceptance testing, periodic verification, comparative evaluations, and for documentation of guaranteed machine accuracy.

Related standards

The ISO/TC 39/SC 2 committee maintains the 10791 series.

FAQ

Q: What is this standard?

A: ISO 10791‑1:2015 is the ISO international standard that specifies geometric test conditions and procedures for machining centres with a horizontal spindle (horizontal Z‑axis).

Q: What does it cover?

A: It covers geometric verification tests (positioning, straightness, squareness, angular errors) for three‑axis NC machining centres and common table/rotary/tilting configurations; it defines applicable axis travel limits and test setups but does not cover accessory spindle heads or operational (non‑geometric) testing.

Q: Who typically uses it?

A: Machine tool manufacturers, test/calibration laboratories, procurement and acceptance engineers, OEM service teams, and metrology/quality departments use it for acceptance testing, performance specification and verification.

Q: Is it current or superseded?

A: ISO 10791‑1:2015 is the current published edition (Edition 2, 2015) and has been subject to ISO periodic review — the ISO bibliographic record shows the 2015 edition as the active published version. Users should check national bodies or ISO for the latest status before formal use.

Q: Is it part of a series?

A: Yes — ISO 10791 is a multipart series covering test conditions for machining centres (parts addressing vertical spindles, positioning accuracy, feeds/speeds/interpolations, finished test pieces, contouring, thermal effects, etc.). See the ISO 10791 series index for the full list of parts.

Q: What are the key keywords?

A: machining centre; geometric tests; horizontal spindle; positioning accuracy; ISO 10791; CNC metrology; axis travel limits; ISO 230.
