“…The measurement instrument using laser sensor [5] is particularly suitable for measuring the drill flute as a three-dimensional concave surface. But, scanning its cross-section directly is impossible, due to the variation of surface normal directions [6]. For some segment on the cross-sectional profile, the incident angles (angle between the laser beam and the surface normal) may be out-off limit (smaller than 30°).…”

Accurate measurement for the flute curve of drill is essential to its design and the evaluation of cutting performance of drill. The helical flute curve of the drill has a big influence on the shape of the　main blade, the exhaust of the chip, and the supply of the coolant etc. In this paper the measuring method of flute curve is described. As the measuring method,　the lead, helical angle, normal section shape (flute curve) was measured respectively. Then the measured data are analyzed with digital filtering, smoothing etc., thus the normal section shape and cross-section shape data are gained. The measured data agree well with the known values. The proposed measuring method may be applied not only to the measurement of flute curve of the drill but also to the measurement of the other helical flute curves.

“…Automated laser scanning measurement is an expected technique as it is efficient for inspecting complex profiles. However, because several difficult problems such as automatic planning of scanning line and measurement accuracy have not been solved completely, research efforts so far have been focused on applying the technique to inspect profiles in a known form, for example, a Measurement of Free Form Surfaces on Machining Centers contour defined by a CAD model, rather than those in unknown forms [10][11][12][13][14][15]. Furthermore, with the progress of micro/nano metrology, some ultra-precision 3D contour form measuring devices are commercially available for inspecting the surfaces of precision products such as aspheric lenses and semiconductor wafers [16][17][18].…”

The paper presents research on the improvements over an autonomous non-contact device with a vertical spindle for free form measurement which the authors developed previously. The fundamental ideas in the previous work include combining two displacement sensors with a servo motor, keeping the position of the sensor to directly measure the surface at the central value of the sensor's measuring range by controlling the motor rotation and performing scanning motions with NC functions of a MC. The inspection is entirely independent of the NC apparatus of the MC. Taking into account both the measurement accuracy and efficiency, three major improvements have been made retaining the advantages of the device. These improvements include 1) introducing a new sensing method for reference position along a scanning line to separate the reference position detection from the contour profile measurement, 2) accepting an AC servo motor controlled by a speed rule to raise the capability of autonomous movement following the contour profile to be measured, and 3) adopting a new laser displacement detector to widen the applicable range for both the shape and material of the surface to be measured. To assess the performance of the improved device, verification experiments are carried out on a machining center with several samples made of different materials. The experiment results demonstrate the effectiveness of the improvements made on the device.

“…There is a substantial body of literature regarding surfaces' intersection [1][2][3][4]. The methods provided are directly applicable to flank/flute intersection of standard drill [5], where the flank is a conic surface and the cutting edge is a straight line. In addition, this line starts at a definite position from which all other points on the cutting edge can be explored consecutively.…”
