RESULT AND DISCUSSION

As a result of the experiment, measured shape is shown in Figure 7. The variation of the data obtained
by the measurement was 8 urn. The formula of Ra (ISO 1302: 2002) was used as the evaluation
method of variation. It has confirmed that smooth execution of the system is seen from measurement
result. Additionally, it was shown that metal surface measurement is possible. The result shows the
feasibility of measurement system with laser displacement sensor and machine's coordinates as a
reference.

CONCLUSIONS

In order to achieve On-machine measurement with laser displacement sensor on 5-axis machining
center, a system for On-machine measurement based on using additional two rotary axes on a 5-axis
machining center is proposed in this paper. The conclusions are as follows:
(1) We explained the concept of a measurement method with laser displacement sensor on a 5-axis
machining center.
(2) We confirmed feasibility of developed system by validation experiment.
