When the position of the first workpiece clamp 253 is set to absolute coordinates (0, -y, 0) in the state shown in FIG. 1, the scale 410, the right side is + X-axis direction, The left side is the -X axis direction, the origin is (0,0,0) in front + y, the front is the + Y axis direction, the direction of tilting the front side of the first side rail 242 upward + X Axial rotation direction, the opposite direction is -X axis rotation direction, the direction to rotate the front end of the first object to be fixed 253 to the right is + Z axis rotation direction, the opposite direction is -Z axis rotation direction, etc. Without using electronic components, the user can accurately recognize the direction and the displacement.

The interface means 500 may determine the relative or absolute coordinates of the first object to be fixed 253 and the processing tool 351 or the second object to be fixed 353 via the coordinate recognition means 400. It is a means for transmitting to the computer processing means 600.

The computer processing means 600 is a means for processing the coordinate values measured by the coordinate recognition means 400 on the computer, may be embedded in the base 100 or the like separately provided, the computer processing means 600 For details of the work performed by the), the computer processing unit 600 will be described separately in each part for describing the related content.

24 is a perspective view illustrating a structure in which the first workpiece M1 is fixed to the first workpiece fixture 253, and FIG. 25 is a first workpiece M1 using a contact probe 352. It is an enlarged perspective view of the main part shown in order to demonstrate the structure which detects the marking point P given to this.

Referring to FIG. 25, the contact probe 352 may be mounted to be replaced by the machining tool 351, or may be mounted to the second rail stand 340 together with the machining tool 351. Through the process of contacting the probe 352 to the label of the first object M1, the position of the label point P is extracted from the label (not shown) given to the first object M1. In the coordinate system of the multi-axis processing machine according to the embodiment of the present invention can be obtained in absolute coordinates.

A label is formed on a contact portion with the contact probe 352 on the first processing object M1, and the coordinate recognizing means 400 is a label point P on the label contacted with the contact probe 352. Recognizing the absolute coordinate of the contact point, the computer processing means 600 receives the absolute coordinate of the mark point (P) through the interface means 500 and then based on the absolute coordinate of the mark point (P). The target coordinates (coordinates of the processing vector included in the three-dimensional image data of the first processing object M1) of the first processing object fixture 253 are calculated.

The first processed object M1 to which the label is attached may acquire three-dimensional coordinate data with respect to its appearance and position information of the label by using a three-dimensional scanning apparatus such as a three-dimensional CT. Directly attach the label to M1, or when the medium (for example, the first processing object M1) coupled to the first processing object (M1) is an intraoral impression model, the tray engraved the shape of the teeth and gingiva (T) (see FIG. 25) can be indirectly given a label.

By inputting the three-dimensional coordinate data of the first processing object M1 acquired through the above process into a computer and performing a machining simulation, an optimal machining plan can be established and derived as three-dimensional coordinate data. The processed machining plan may be stored as data of a three-dimensional machining vector defining a machining content of the first machining object M1.

Since the three-dimensional coordinate data of the first object M1 is obtained from a three-dimensional scanning apparatus having a coordinate system separate from that of the multi-axis machine, the multi-axis machine according to the embodiment of the present invention is the first object M1. It has its own unique coordinate system that is not related to the three-dimensional coordinate data of) and the coordinate system of the machining vector. Applying the machining vector established by simulation on a multi-axis machine according to an embodiment of the present invention as it is. In order to do this, the coordinate system needs to coincide with each other.

The mark point P serves as a reference point for matching the three-dimensional coordinate data of the first object M1 acquired by the coordinate system of the three-dimensional scanning apparatus with the coordinate system of the multi-axis processing machine according to the embodiment of the present invention.

That is, the coordinates of the tip of the contact probe 352 have a known value on the coordinate system of the multi-axis processing machine according to the embodiment of the present invention, and the first machining contacted with the contact probe 352. 3D coordinate data of the first object M1 by matching one point (the mark point P) on the object M1 with the coordinates of the tip of the contact probe 352. It is possible to match the coordinate system of the multi-axis processing machine according to an embodiment of the present invention.

Calculating a coordinate shifting matrix for moving the coordinates of the mark point P on the three-dimensional image data of the first processing object M1 to the coordinates of the mark point P on the multi-axis processing machine according to the embodiment of the present invention; When the calculated coordinate shift matrix is applied to the three-dimensional image data and the processing vector data of the first processing object M1, the three-dimensional image data and the processing vector data of the first processing object M1 are applied. It can be implanted into the coordinate system of the multi-axis processing machine according to the embodiment.

Referring to FIGS. 24 and 25, the label on the first processing object M1 is reliably extracted so as to reliably extract the mark P as a reference point of the coordinate transformation as described above using the contact probe 352. It is preferably formed in a positive or negative shape, the tip of the contact probe 352 is preferably formed in a shape complementary to the label.

Preferably, the number of the labels to be given to the first processing object M1 is selected to be three, and the minimum and minimum positions for defining the position and the direction (rotation) of the first processing object M1 occupying a three-dimensional space. If the number of coordinates is 3 and there are atypical three or more coordinates that do not form a single plane, the data of _n C ₃ (where n is the number of selected coordinates, which is a natural number of n> 4) must be fitted together. This is because it is inefficient.

In forming a label on the first object M1, the center of the circle obtained from the coordinates of three points (three mark points P) selected in the outline of the first object M1 is newly created. When located outside of the machining portion of the first workpiece M1 with respect to the geometric center of the first workpiece M1 so as to determine the mark point P, one circle is extracted from three points. The center of the circle can be determined as the new reference mark point (P). The reason why it is preferable to position the label outside the machining portion of the first workpiece M1 with respect to the geometric center of the first workpiece M1 is because one plane is extracted by three marker points. This is because the presence of the machining part inside the reference point of extraction is advantageous in terms of error. This is the same reason that the interpolation method has less error than the extrapolation method in the interpolation method.

According to an embodiment of the present invention, the contact probe 352 is transmitted to the coordinate recognition means 400 that the contact with the label formed on the outer surface of the first processing object (M1) and the fraudulent contact probe 352 and It may further include a trigger means 700 for instructing to recognize the absolute coordinate of the mark point (P) determined by the contact of the mark.

Accordingly, when the user determines that the touch probe 352 and the label are in tangible contact, the trigger means 700 may be operated to acquire the coordinates of the mark point P at the corresponding point in time.

The trigger means 700 may be provided with a mode change function that can be set to switch between a first mode instructing to recognize the absolute coordinates of the mark point and a second mode instructing to drive the machining tool drive means. have.

Accordingly, when the contact probe 352 is mounted, the mode change switch (not shown) of the triggering means 700 is set to the first mode to obtain the coordinates of the mark point P. When the machining tool 351 is mounted, the mode change switch may be switched to the second mode to operate the machining tool driving means.

When the trigger means 700 is configured, the interface means 500 can be transmitted and received to the outside of the base 100 and configured as a kind of foot switch configured to issue a command by a user's foot motion. By using the movable stand 200 or the fixed stand 300, a user who is manually operating the trigger means 700 may be conveniently operated by using a foot.

On the other hand, it is also possible to convert the three-dimensional coordinate data of the first workpiece M1 into absolute coordinates in the coordinate system of the multi-axis processing machine without using the contact probe 352, which is special on the first workpiece fixture 253. It may consist of providing a label having a geometric meaning.

Referring to the embodiment of the first workpiece fixture 253 shown in FIG. 24, three markers protrude in a positive shape on the upper surface of the body of the first workpiece fixture 253 having a plate shape. Correspondingly, a negative cavity having a shape complementary to the shape of the label is formed on the bottom of the first processing object M1. Therefore, the first workpiece M1 is always fixed to the first workpiece fixture 253 in a predetermined direction and position, which is the absolute coordinate of the negative cavity formed on the bottom surface of the first workpiece M1 in the coordinate system of the multi-axis machine. Means that it is already set.

In addition, since the three-dimensional coordinate data obtained by three-dimensional scanning of the first workpiece M1 includes negative cavity data, it is possible to incorporate the coordinates of the machining vector into the coordinate system of the multi-axis machine using the negative cavity data. If this is described in more detail as follows.

Even if the 3D image data of the first processing object M1 is obtained according to an independent coordinate system of the 3D scanning apparatus, the image data includes negative cavity data, and all image data other than the negative cavity are coordinates of the negative cavity. Since it may be defined as a relative coordinate with respect to, all three-dimensional image data of the first processing object M1 may be implanted in the coordinate system of the multi-axis processing machine.

Wherein the shape of the label of the negative cavity, that is, the first processing object fixture 253 having a shape complementary thereto is the same as described above. That is, when the shape of the label is determined so that one circular plane (reference circle) can be extracted from the coordinates of three points selected from the surface contour of the protruding portion of the label, two coordinate systems (coordinate systems of the three-dimensional scanning apparatus and the multi-axis processing machine) ) Can be synchronized by mutually matching the coordinates of the center of the reference circle and the vector of the plane to which the reference circle belongs in three-dimensional space.

The selection of the three coordinates is as described above because the minimum number of coordinates for extracting the circle from the spatial coordinates is as described above, and one embodiment which can be used as such a marker is three pillars as shown in FIG. 24. As a projection of a shape, the contour of the upper surface or the base surface of a projection is made into the shape which can extract a circle. Therefore, in this case, the three coordinates for determining the reference circle are the centers of the circles respectively extracted from the contours of the top surface or the bottom surface of the three projection-shaped labels. Here, determining the coordinates (center of the circle) from the base surface contour of the label is based on the first object M1 in which a negative cavity having a shape complementary to the protruding label is generated. It has the same meaning as determining coordinates from the baseline contour of a negative cavity located on the surface.

There are numerous shapes available for the contour of the top or base surface of the label from which one circle can be extracted. Most intuitively, it may be a circular contour as shown in FIG. 24, or may be a polygonal contour inscribed or circumscribed to a circle that may be represented by an equilateral triangle. In the case of a polygon, three coordinates may be obtained from three vertices selected from a plurality of vertices of a polygon. Here, the shape of the polygon may be a regular polygon that is easy to numerically calculate and verify and to intuitively recognize the center of the circle.

In addition, the reverse method of forming the label formed on the first object to be fixed 253 as a negative cavity and forming a positive protrusion on the first to be processed M1 is possible, and the second object to be fixed 353 is the same. Of course, it can be configured.

On the other hand, if the first processing object M1 can always be fixed to the first processing object fixture 253 in a predetermined direction and position, the first processing object M1 without forming a label on the first processing object fixture 253. It is possible to convert the three-dimensional coordinate data of the first processing object M1 into absolute coordinates in the coordinate system of the multi-axis processing machine only by forming a negative or positive label only. That is, as illustrated in FIG. 24, if the fixed position of the first processing object M1 can be constantly reproduced by forming a jaw protruding along the circumference of the first processing object fixing tool 253, the multi-axis The absolute coordinate of the first workpiece M1 in the coordinate system of the machine will always remain constant, which means that the absolute coordinate of the label formed at the predetermined position on the first workpiece M1 is also a known value. Because. Since the number, shape, and the like of the label included in the first processing object M1 are the same as described above, the description thereof will be omitted.

Accordingly, a user applies the lifting bar 366 to the second column 320 by applying a rotational force in the Z-axis direction to a part of the rotation control tool 364 exposed to the outside of the second column 320. It can move up and down in the Z-axis direction through the upper part.

The second rail stand 340 may be provided with a rotary encoder for sensing a rotational displacement in the Z-axis direction of the machining tool 351 or the second object to be fixed 353.

The resolution of the encoder 420 is preferably about 0.01 mm for the linear encoder and about 0.01 ° for the rotary encoder. Although the resolution of the encoder 420 may be further increased, an error may be generated due to a sensitive response to noise, and a sensitivity may be affected by measurement and control. Therefore, adjusting the resolution to an appropriate level in software in consideration of processing precision is required. desirable.

By installing a plurality of the encoder 420 in the base 100, the first column 220, the second column 320, the first side rail 242, the second side rail 340 as described above, the X The linear displacement in the axial direction, the Y-axis direction and the Z-axis direction, and the rotational displacement in the Z-axis direction can be automatically and accurately recognized.

If the user can recognize the linear displacement and rotational displacement in the + X, -X, + Y, -Y, + Z, and -Z axis directions, the user is not limited to a specific means including a beep.

The computer processing means 600 compares the target coordinates of the first target object fixture 253 and the current coordinates with each other, and then directs the instruction data indicating the direction of movement to converge toward the target coordinates. And the interface means 500 may output a driving signal corresponding to the transmitted indication data to each of the motion indicators 800.

As described above, when the light emission of the motion indicator 800 is controlled, the indicator of the motion indicator 800 corresponding to the direction toward the target coordinate during processing is automatically emitted, so that the user indicates that the motion indicator 800 emits light. The first workpiece M1 may be positioned at the correct machining position by moving the moving stand 300 or rotating the first workpiece fixator 253 in the direction.

The computer processing unit 600 causes the motion indicator 800 to display a neutral signal when a difference between a target coordinate and a current coordinate of the first object to be processed 253 is within a preset error range. By transmitting the termination data to the interface means 500, it is possible to easily recognize that the user has reached the target coordinates.

The neutral signal includes all signals that enable the user to recognize that the user has reached the target coordinate, such as turning on some or all of the plurality of motion indicators 800, flashing intermittently, or changing the color of light emitted. It is also possible to beep with a buzzer.
