Test code for machine tools - Part 3 : determination of thermal effects

ISO 230-3:2007 defines three tests for the determination of thermal effects on machine tools: an environmental temperature variation error (ETVE) test, a test for thermal distortion caused by rotating spindles, and a test for thermal distortion caused by moving linear axes.The test for thermal distortion caused by moving linear axes is applicable to numerically controlled (NC) machines only and is designed to quantify the effects of thermal expansion and contraction as well as the rotational deformation of structure. For practical reasons, it is applicable to machines with linear axes up to 2 000 mm in length. If used for machines with axes longer than 2 000 mm, it will be necessary to choose a representative length of 2 000 mm in the normal range of each axis for the tests.The tests correspond to drift tests according to ISO/TR 16015 and define the evaluation and the detailed procedure for machine tools.

Test code for machine tools - Part 3 : determination of thermal effects

ISO 230-3:2007 defines three tests for the determination of thermal effects on machine tools: an environmental temperature variation error (ETVE) test, a test for thermal distortion caused by rotating spindles, and a test for thermal distortion caused by moving linear axes.

The test for thermal distortion caused by moving linear axes is applicable to numerically controlled (NC) machines only and is designed to quantify the effects of thermal expansion and contraction as well as the rotational deformation of structure. For practical reasons, it is applicable to machines with linear axes up to 2 000 mm in length. If used for machines with axes longer than 2 000 mm, it will be necessary to choose a representative length of 2 000 mm in the normal range of each axis for the tests.

The tests correspond to drift tests according to ISO/TR 16015 and define the evaluation and the detailed procedure for machine tools.

Test code for machine tools - Part 3 : determination of thermal effects

La présente partie de l'ISO 230 définit trois essais qui sont: - l'essai d'erreur due à des variations de la température ambiante (ETVE); - l'essai de déformation thermique due à une broche en rotation; - l'essai de déformation thermique due au mouvement le long d'un axe linéaire. Les essais de déformation thermique due à un mouvement linéaire (voir article 7) s'appliquent uniquement aux machines à commande numérique (CN) et sont destinés à mesurer les effets des dilatations et contractions thermiques d'un axe sur l'exactitude du positionnement et sur la répétabilité. Pour des raisons pratiques, les méthodes d'essai décrites dans l'article 7 s'appliquent à des machines à axes linéaires d'une longueur inférieure ou égale à 2 000 mm. Si ces essais sont réalisés sur des machines dont les axes dépassent 2 000 mm de long, il est recommandé de déterminer pour les essais une longueur représentative de 2 000 mm dans la plage normale de chaque axe. Il convient de noter qu'il n'est pas prévu de fixer des valeurs de tolérances pour les essais décrit dans la présente partie de l'ISO 230.

Test code for machine tools - Part 3 : determination of thermal effects

This document defines four tests: — an environmental temperature variation error (ETVE) test; — a test for thermal distortion caused by rotating spindles; — a test for thermal distortion caused by moving linear axes; — a test for thermal distortion caused by rotary motion of components. The tests for thermal distortion caused by moving linear axes (see Clause 7) are applicable to numerically controlled (NC) machines only and are designed to quantify the effects of thermal expansion and contraction as well as the angular deformation of structures. For practical reasons, the test methods described in Clause 7 apply to machines with linear axes up to 2 000 mm in length. If they are used for machines with axes longer than 2 000 mm, a representative length of 2 000 mm in the normal range of each axis is chosen for the tests. The tests correspond to the drift test procedure as described in ISO/TR 16015:2003, A.4.2, applied for machine tools with special consideration of thermal distortion of moving linear components and thermal distortion of moving rotary components. On machine tools equipped with compensation for thermal effects these tests demonstrate any uncertainty in nominal thermal expansion due to uncertainty of coefficient of thermal expansion and any uncertainty of length due to temperature measurement.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
