Inspection of Free Form Surfaces on Machining Center

Abstract

In this paper, an autonomous measuring principle, in which two sensors with different purpose are combined with a servo motor, is proposed. A prototype device able to apply to machining center has been conducted. Attaching the device with the spindle and feeding the work piece set on the table of a machining center, the device can automatically follow the contour and measure its form along the scanning lines. Several measurement results sufficiently demonstrated the effectiveness of the proposed principle and developed device.
