Purpose: Both the results obtained previously relating to structure dynamics of a simultaneous five-axis movement machine tool and to the investigations on dynamic cutting behavior are further applied as a foundation to study the effect of the process parameters on the cutting stability in the process of a complicated free surface machining. Design/methodology/approach: In the paper cutting stability investigation on a complicated fee surface machining are described. Findings: The experimental data obtained from the cases with and without a real cutting process find that a test under a specified rotational speed can generate its own charcteristic 3-direction frequencies. The paper specially select the characteristic frequency with the most significant change on response amplitude to analyze. Practical implications: The investigation procedures and the results obtained may be used as a reference and guidance for the analysis of cutting stability in the five-axis machining of a complicated surface in industrially practical use. Originality/value: The results shown on frequency domain for identifying characteristic frequencies can be interpreted on time domain to observe amplitude variation respect to time and further understand its changing pattern under the cutting process.
