BS 3800 is a British standard that discusses general tests for machine tools. BS 3800-3 is the third part of the multi-part series that outlines the methods for assessing the contribution to workpiece inaccuracy arising from the thermal behaviour of the machine, due to internal heat sources, in respect of:
The tests for thermal distortion of the structure under BS 3800-3 apply to any machine which incorporates a rotating spindle or spindles supporting the tool or the workpiece.
The tests are designed to establish the relative displacements occurring between the tool and workpiece sides of the structure because of thermal expansion or contraction of key structural elements.
The tests for thermal drift of the axis drives apply to numerically controlled (NC) machines only and are designed to quantify the effects on positioning accuracy and repeatability of thermal expansion and contraction of the axis drives.
BS 3800-3 on the performance of machines operating under loaded conditions in respect of thermal distortion is useful for:
BS 3800-3 assists you with test conditions on the environment, machine to be tested, and sequence of testing for evaluating the performance of machines operating under loaded conditions in respect of thermal distortion.
BS 3800-3 also guides you regarding the thermal distortion of the structure by guiding on instrumentation and equipment, test procedure, and interpretation of results for evaluating the performance of machines operating under loaded conditions in respect of thermal distortion.
BS 3800-3 also guides you regarding the thermal drift of axis drives by providing guidance on instrumentation, test equipment, test procedure, and interpretation of results for evaluating the performance of machines operating under loaded conditions in respect of thermal distortion.
With obedience and compliance to BS 3800-3, you can enhance the performance of machines operating under loaded conditions in respect of thermal distortion.
