Full title and description

Machine tools — Test conditions for testing the accuracy of boring and milling machines with horizontal spindle — Part 3: Machines with movable column and movable table. This International Standard specifies geometric tests, machining tests and numerical-control positioning tests, together with applicable tolerances, for general-purpose, normal-accuracy horizontal-spindle boring and milling machines with a movable column and movable table.

Abstract

ISO 3070-3:2007 defines test conditions (geometric tests, machining tests and NC positioning repeatability) and the corresponding tolerances for verification of the accuracy of horizontal-spindle boring and milling machines having a movable column and movable table. It explicitly excludes operational tests such as vibration or checks of speeds and feeds, which are normally performed prior to accuracy testing.

Scope

Specifies tests and tolerances for verifying the accuracy and repeatability of positioning by numerical control of general-purpose, normal-accuracy, horizontal-spindle boring and milling machines having a movable column and movable table. Applicable machine axes (X, Y, Z and optional U, W) and typical machine configurations are described; the standard deals only with accuracy verification and not with operational characteristics such as vibration, noise or speed/feed performance.

Key topics and requirements

• Definitions of test set-ups and reference conditions for geometric tests (straightness, squareness, parallelism, etc.).
• Machining tests to assess practical accuracy under cutting conditions.
• Tests for NC positioning accuracy and repeatability for relevant axes (X, Y, Z and optional axes U/W).
• Specification of applicable tolerance classes and numerical tolerance values for the prescribed tests.
• Reference to ISO 230 series for general test procedures and conditions to ensure consistency with other machine-tool tests.

Typical use and users

Used by machine-tool manufacturers, independent test laboratories, quality and metrology departments of manufacturing companies, machine-tool purchasers and acceptance-test teams to verify machine accuracy at factory acceptance, installation acceptance and periodic verification. Also used by standards committees and technical writers preparing test procedures and tolerance tables.

Related standards

Directly references and is intended to be used with the ISO 230 series (e.g., ISO 230-1 and ISO 230-2) for general test procedures and environmental/test conditions. Other parts of the ISO 3070 series (historical parts such as ISO 3070-0 and ISO 3070-4) are related background documents; national adoptions (e.g., BS ISO 3070-3) may also exist.

Q: What does it cover?

A: It covers geometric tests, machining tests and numerical-control positioning repeatability tests and specifies the applicable tolerances; it does not cover operational checks like vibration or speed/feed characteristics.

Q: Who typically uses it?

A: Machine manufacturers, acceptance-test engineers, metrology labs, quality departments and purchasers who need to verify machine accuracy at delivery, installation or during periodic checks.

Q: Is it current or superseded?

A: ISO 3070-3:2007 was published in December 2007 (Edition 3) and is listed as published and confirmed within ISO's review lifecycle; users should check national standards bodies for any later amendments or national versions.

Q: Is it part of a series?
