BS ISO 3070-4-1998 PDF

Full title and description

STB BS ISO 3070-4:1998 — Test conditions for boring and milling machines with horizontal spindle — Testing of the accuracy — Part 4: Planer type machines with movable column. This document sets out the methods, test procedures and applicable tolerances for verification of the accuracy of planer-type horizontal-spindle boring and milling machines with a movable column.

Abstract

This part of ISO 3070 specifies geometric and machining tests, and checks for positioning accuracy and repeatability (including numerical-control positioning tests) for planer-type horizontal-spindle boring and milling machines with movable column. It cross-references ISO 230 test-methods standards and gives the applicable test tolerances. The standard deals only with verification of accuracy (geometric and positioning) and does not cover operational characteristics such as vibration, abnormal noise or performance of speeds and feeds. Published in March 1998 (Edition 2), it has since been withdrawn and superseded by later work in the ISO 3070 series.

• Number of pages: 41 pages.

Scope

Applies to general-purpose, normal-accuracy planer-type horizontal-spindle boring and milling machines with a movable column (machines having table movement along X, spindle head vertical movement along Y, and column movement along W; may include rotary or indexing tables). It defines the test conditions, measurement methods and tolerances for verifying geometric accuracy, machining test results and NC positioning repeatability. It does not cover machine operational characteristics (vibration, abnormal noise, speeds/feeds) or acceptance tests outside accuracy verification.

Key topics and requirements

• Definitions and machine-type identification (planer-type horizontal spindle machines with movable column).
• Reference to ISO 230 series test-methods and to ISO 3070‑0 where machine types are defined.
• Geometric tests: straightness, flatness, squareness, parallelism and alignment checks for relevant axes and machine elements.
• Machining tests: practical test cuts to assess machining accuracy under specified conditions.
• NC positioning tests: checks for accuracy and repeatability of numerically controlled positioning.
• Specified environmental and test conditions (measurement systems, mounting, and procedures to ensure repeatable results).
• Applicable tolerances and criteria for compliance for the defined tests.

Typical use and users

Used by machine-tool manufacturers, production and quality engineers, test laboratories, acceptance and inspection bodies, machine-tool purchasers and maintenance teams for verifying and documenting the positional and geometric accuracy of planer-type horizontal-spindle boring and milling machines. Also used by standards committees and accreditation bodies when harmonizing or adopting national editions of ISO test methods.

Related standards

FAQ

Q: What is this standard?

A: It is Part 4 of ISO 3070 (1998) specifying test conditions and accuracy checks for planer-type horizontal-spindle boring and milling machines with a movable column.

Q: What does it cover?

A: It covers geometric and machining accuracy tests, NC positioning accuracy and repeatability, measurement procedures and applicable tolerances for the machine type; it does not cover operational checks such as vibration or speed/feed performance.

Q: Who typically uses it?

A: Machine-tool manufacturers, quality and test engineers, inspection laboratories, purchasers and national standards/adoption bodies use it for accuracy verification and acceptance testing of planer-type horizontal-spindle machines.

Q: Is it current or superseded?

A: This 1998 edition has been withdrawn in the ISO lifecycle and the ISO 3070 family has been revised; users should consult the current part(s) of ISO 3070 (for example later work in the series such as the 2007 revision activity) or their national standards body for the active, superseding document.

Q: Is it part of a series?

A: Yes — ISO 3070 is a multi-part series covering test conditions for boring and milling machines with horizontal spindle; Part 4 is the planer-type machines with movable column segment within that series.

Q: What are the key keywords?

A: Planer-type machine, movable column, horizontal spindle, accuracy testing, geometric tests, machining tests, NC positioning, ISO 3070, ISO 230, tolerances.
