Abstract

The invention relates to a measurement device for a chip removing machine, and methods of obtaining frequency response functions, obtaining stability charts and selecting operational parameters of a chip removing machining tool. The device (1) has a front end (10) and a rear end (11). A centre axis (x) extends between the front end and the rear end. The device comprises an engagement portion (2) at the rear end for engagement with the machine and a measurement portion (5) at the front end, distal to the engagement portion, which measurement portion is without a tool tip. The measurement portion comprises a planar front end surface (6), perpendicular to the centre axis. The front end surface comprising a coupling point (8) aligned with the centre axis, for receiving mechanical excitation. The front end surface further comprises a plurality of seats (9, 9', 9", 9"') for receiving one accelerometer each, for measuring a response of the received mechanical excitation. Each seat comprises three contact surfaces for the accelerometer such that when an accelerometer is received in one of the seats, and abutting against the three contact surfaces, it is positioned and oriented in three dimensions in space and around three axes of rotation in relation to the coupling point.
