摘要： PROBLEM TO BE SOLVED: To provide a formation method for forming an accurate chatter stability limit diagram, the method which is capable of maximizing a setting range of machining conditions that allow machining without generating chatter vibration.SOLUTION: Stiffness values and damping coefficients calculated while a tool 2 remains stationary are used to form a provisional chatter stability limit diagram. Chatter vibration during machining is measured by a vibration measurement device 4 while changing the rotational speed of a main spindle 1 in the vicinity of a prescribed peak of the provisional chatter stability limit diagram in order to detect the rotational speed of the main spindle that the frequency of the chatter vibration suddenly changes. The chatter stability limit diagram is formed by moving the position of the prescribed peak of the provisional chatter stability limit diagram to the rotational speed of the main spindle that the frequency of the chatter vibration suddenly changes.

摘要： PROBLEM TO BE SOLVED: To provide an on-machine shape-measuring apparatus capable of measuring the surface shape of a work piece, while and making it contact the measurement probe at low-contact pressure. SOLUTION: The on-machine shape measuring apparatus 30 measures the vibration components in the locked state of a servo-motor before starting the measurement (S14), sets up the notch filter 66 for removing the vibration components (S18), removes the machine vibration components in the locked state etc., of the servomotor by the set notch filter 66 (S20) from the output of a linear scale 44, after starting the measurement.
