き付けることが望ましい。The dust removal method according to the present invention is a method using air blowing, but the conventional dust removal method using air blowing generally involves blowing air over the entire surface of the target material. In other words, on a relatively flat surface, dust could be sufficiently removed even if the air was sprayed on the entire surface by carefully controlling the locations and directions. However, such rough blowing of air cannot sufficiently remove dust from the surface of objects with complex three-dimensional shapes, such as multi-blade cutting tools such as end mills. For example, when measuring the outer diameter dimension of the cutting edge of a multi-blade cutting tool, sufficient measurement accuracy cannot be achieved due to the influence of dust. In other words, the outer diameter of a multi-blade cutting tool such as an end mill is the diameter of the circle that passes through the tip of each cutting edge. -) 1 F
Option 2 Therefore, if air is blown over the entire tool, there is a risk that dust, etc. that has adhered to positions other than the cutting edge will re-adhere to the tip of the cutting edge, and the cleaning effect will not be improved, and such problems may occur. In order to eliminate this problem, it is desirable to blow air only at the tip of the cutting blade.

a first step of setting an initial position so that the axial tip of the cutting blade formed at a predetermined helix angle on the circumferential surface of the multi-blade cutting tool faces the air outlet of the air nozzle; A second step includes blowing air over the entire length of the cutting blade while maintaining the facing state of the blade and the air nozzle outlet while relatively moving at least one of the tool or the air nozzle. In this second step, the air nozzle may be fixed and the tool may be rotated around its axis and fed in the axial direction, or the tool may only be rotated around its axis and the air nozzle may be moved in the axial direction of the tool. I can work. To take an extreme example, the air nozzle may be pivoted around the axis of the tool and the tool may be given only axial feed, the requirement being that either the air nozzle or the tool is in motion (or both are in motion). It can be spiral or straight (with a given helix angle,
For example, the motion system of the air nozzle is controlled so that the outlet of the air nozzle always faces the cutting edge of the tool, which extends at an angle of 0° (as in the case of a parallel-blade gluer).

This will be explained with reference to the figures. FIG. 1 is a schematic diagram showing the configuration of an apparatus for implementing the method according to the present invention. In the figure, numeral 1 is a multi-blade cutting tool (hereinafter simply referred to as a tool) such as an end mill, which is the object of dust removal. The circumferential surface thereof has a cutting edge at a predetermined helix angle. The shank, which is the shaft end, of the tool i is fixed and held by the jacking jig 2 when the dust is removed. The jacking jig 2 also includes a feed motor 3 that moves the held tool l along with the jig 2 in its axial direction.
and a rotary motor 4 for rotating the tool 1 around its axis.The nozzle 5 is arranged with its Suita mouth 5a facing on the axis in the feeding direction of the tool 1. Furthermore, a cutting edge position detector 6 is provided at a position a predetermined distance away from the air nozzle 5, and has a detection portion facing along the axis of the tool 1 in the feeding direction, similarly to the air nozzle 5. This cutting edge position detector 6 is the axis of the cutting edge of the tool l. Any device can be used as long as it can detect the position of the directional tip, and for example, an optical outer diameter measuring device or an eddy current displacement meter can be used. To actually set the initial position of the tool 1, move the tool 1 to the position of the cutting edge position detector 6 using the feed motor 3, then rotate the tool 1 around its axis using the rotary motor 4, and move the tool 1 to the position of the cutting edge position detector 6. Stop rotation with the axial tip pointing directly upward. The initial position is set by moving the tool 1 by the feed motor 3 until the tip of the cutting edge of the tool 1 comes directly below the air nozzle 5. Air blowing is performed by simultaneously feeding the tool l in the axial direction and rotating it around the axis by the feed motor 3 and the rotary motor 4, with the cutting edge always facing the air outlet 5a of the air nozzle 5. Moving. The axial feed rate and rotational speed around the axis of the tool 1 are set in advance according to the helix angle of the cutting edge, and are input into the microcomputer 7. In addition, if the nominal diameter of the tool 1 is known, such as when dealing with a cutting tool carried out from a numerically controlled processing machine, the shape of the cutting edge of the tool 1 is uniquely determined, and the shape of the cutting edge of the tool 1 is uniquely determined, and The relationship between the feed rate and the rotational speed around the axis can be manually entered into the microcomputer 7 in advance. In the figure, 38 is a motor driver that controls and drives the feed motor 3 based on the output of the microcomputer 7, and similarly, 48 is a motor driver that controls and drives the rotary motor 4. Furthermore, 5a is an air supply source for the air nozzle 5, and 5b is an air supply source drive controller. FIG. 2 is an explanatory diagram showing an example of the arrangement of air nozzles in a modified embodiment of the dust removal method according to the present invention. In the above embodiment, only one air nozzle 5 is provided, so initial position setting operations must be performed for the number of blades of the multi-blade cutting tool, but as shown in FIG. However, by arranging the air nozzles 5 at positions corresponding to the respective blades, dust can be removed from all the cutting blades in a single initial position setting operation. Furthermore, if dust is to be removed only to measure the outer diameter of a multi-blade cutting tool, it is sufficient to remove dust only from the cutting edge in the area to be measured.
