IS 9809 : 1981 Test chart for crankshaft grinding machines

1 Scope - Describes both geometrical and practical tests on crankshaftgrinding machines and the corresponding permissible deviations withreference to IS 2063 : 1962 `Code for testing machine tools`.

1.1 It deals only with the verification of accuracy and appliesneither to the testing of the running of the machine (vibrations,abnormal noises, stick-slip motion of components, etc) nor to themachine characteristics (speeds, feeds, etc) which shall generallybe checked before testing the accuracy.
