BS ISO 19744:2020 pdf free.Test conditions for numerically controlledbroaching machines — Testing of accuracy —Vertical surface type broaching machines.
This document specifies, with reference to ISO 230-1, the geometric tests on numerically controlled(NC) broaching machines of normal accuracy, with vertical axis acting for cutting operation. Theaccuracy of rotary axes, if available, is checked with reference to ISO 230-7.
This document also specifies, with reference to IS0 230-2, the positioning tests on vertical surface typebroaching machines for both linear and rotary axes.
This document proposes test pieces containing broached slots and grooves with reference to lSO 230-1,cutting tests under finishing conditions. It also specifies the characteristics and dimensions of thetest pieces themselves. This document is intended to supply minimum requirements for assessing thecutting accuracy of the machine.
This document also establishes the tolerances for the test results corresponding to general purposeand normal accuracy vertical surface type broaching machines equipped with numerical control.
This document explains different concepts or configurations and common features of NC verticalsurface type broaching machines which are normally used in the manufacturing of turbine disks.It alsoprovides a terminology and designation of controlled axes with reference to IS0 841.
This document deals only with the verification of the accuracy of the broaching machine. It does notapply to the operational testing of the machine (e.g. vibration, abnormal noise, stick-slip motion ofcomponents), nor to machine characteristics (e.g. speeds, feeds) as such checks are generally carriedout before testing the accuracy.The following documents are referred to in the text in such a way that some or all of their contentconstitutes requirements of this document. For dated references,only the edition cited applies. Forundated references, the latest edition of the referenced document(including any amendments) applies.ISO 230-1:2012,Test code for machine tools — Part 1: Geometric accuracy of machines operating underno-load or quasi-static conditionsISO 230-2:2014,Test code for machine tools – Part 2:Determination of accuracy and repeatability ofpositioning of numerically controlled axes.BS ISO 19744 pdf download.
