What is ISO 230‑3 about?
ISO 230‑3 is part three of the multi-series standard that defines four 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
- 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.
ISO 230‑3 helps you determine the thermal effects on machine tools.
Who is ISO 230‑3 for?
ISO 230‑3 on test code for machine tools, determination of thermal effects on machine tools is useful for:
- Machine tools designers
- Machine tools manufacturers
Why should you use ISO 230‑3?
ISO 230‑3 specifies test procedures to determine thermal effects on machine tool caused by a variety of heat inputs resulting in the distortions of a machine tool structure or the positioning system.
ISO 230‑3 can be used either for testing different types of machine tools (type testing) or testing individual machine tools for acceptance purposes.
ISO 230‑3 provides you with the test method for environmental temperature variation error, thermal distortion caused by rotating spindle, thermal distortion caused by linear motion of components and thermal distortion due to rotary motion of components.
What’s changed since the last update?
BS ISO 230‑3:2020 is the third edition that cancels and replaces the second edition (ISO 230‑3:2007), which has been technically revised.
The main changes compared to the previous edition is the addition of Clause 8 for checking thermal effects of machine tool rotating heads and tables.
