The coordinate measuring machine 2 and N in the present embodiment
Since the C processing machine 1 uses a master pallet or a work pallet, a chuck (not shown) for fixing these pallets is attached. The coordinate systems of the coordinate measuring machine 2 and the NC processing machine 1 are defined as follows. Coordinate system of coordinate measuring machine 2: x, y, z Coordinate system of master pallet reference in coordinate measuring machine 2:
x ', y', z'Machine coordinate system of NC processing machine 1: X, Y, Z Coordinate system of master pallet reference in NC processing machine 1:
X ′, Y ′, Z ′ The coordinate system finally used in the NC processing machine 1 is:
X ", Y", Z "

As is known, chucks for fixing pallets are attached to the surface plate of the coordinate measuring machine 2 and the table of the NC processing machine 1, respectively, and the master pallet is attached to the chucks. This master pallet is provided with a reference hole, a height reference plane, and a reference plane for confirming the parallelism of the X axis and the Y axis. The chuck is adjusted and fixed so that the surface is parallel to the coordinate system of the coordinate measuring machine 2 and the machine coordinate system of the NC processing machine 1. In this operation, both the coordinate measuring machine 2 and the NC processing machine 1 use the same master pallet and are mounted in the same direction for adjustment.

Next, using the above master pallet, the center of the reference hole formed in this master pallet and the height (Z)
A new coordinate system in which the reference plane is measured and the origin obtained is the point obtained from the measurement result is set to (x ′,
y ′, z ′), and for the NC processing machine 1 (X ′,
Y ′, Z ′) (step 1 (ST of FIG. 4)

Specifically, the master pallet is formed with a reference hole for defining the XY axis at the axial rotation center position of the pallet to be the Z axis, and by measuring four points in the XY directions, the XY coordinate value is obtained. , And the Z coordinate value is determined by measuring the Z reference plane separately determined, and the coordinate value of the reference point of the master pallet in the absolute coordinate system of the coordinate measuring machine 2 (x0, y0, z0) Is required. In the coordinate measuring machine 2, the points (x0,
y0, z0) as a new coordinate system, that is, the coordinate system (x ', y',
z ') is provided.

Similarly, using the same master palette as the one used in the coordinate measuring machine 2, the coordinate values (X0, Y0, Z0) of the reference points of the master palette in the absolute coordinate system of the NC processing machine 1 are calculated. A new coordinate system, which is obtained in advance and whose origin is the point (X0, Y0, Z0) obtained from this measurement result, that is, the coordinate system (X ', Y', Z ') of the master pallet reference in the NC processing machine 1 ) Is provided.

The measurement data storage unit 42 and the processing machine data storage unit 43 need only be able to perform necessary control such as taking out necessary data when necessary.
The control personal computer 4 and the NC processing machine 1 do not necessarily have to be fixedly configured as a storage unit. For example, the processing machine data storage unit 43 may be stored in a storage unit provided in the control personal computer 4. Alternatively, it may be stored in another control unit.

Next, the work to be actually processed is fixed to a pallet, and this pallet is attached to the chuck of the coordinate measuring machine 2 (step 2 (ST2) in FIG. 4).

Here, as described above, the measurement program unit for measuring the machining reference position data is stored in the measurement menu section 411 in the measuring machine software storage section 41 shown in FIG. From the measurement menu section 411 using the external device 5 such as the keyboard 51 and the monitor display 52 to call each measurement program unit represented by the screen display mark 60 shown in FIG. 3, and based on the content to be measured. A corresponding measurement menu is selected from the measurement menu section 411 and the reference position (reference point) of the work is measured by the three-dimensional measuring machine 2 (step 3 (ST3) in FIG. 4). At this time, the work is attached so that the direction of the coordinate system used in the NC machining program and the coordinate system of the three-dimensional measuring machine 2 are parallel, and if necessary, fine adjustment is performed so that the two coordinate systems are parallel. Leave.

In the measurement of the machining reference position data for the workpiece, the reference position measured using the external device 5 is named as a point name, and the point name is
By storing the measured results of the X-axis, Y-axis, and Z-axis together with the measured data in the measurement data storage unit 42, the measurement data can be collected even if the measurement order is performed regardless of the actual processing order.

The coordinates of the machining reference position (reference point) of the workpiece here are the coordinates (x'1,
They are collectively referred to as y'1 and z'1). Further, the coordinates (x'1, y'1, z'1) of the machining reference position of the workpiece do not necessarily have to be measured at the workpiece machining reference point by selecting the measurement menu from the measurement menu section 411. Alternatively, the reference point of the work may be measured separately from the measurement menu of the measurement menu unit 411.

Next, by the data conversion unit 44 provided in the control personal computer 4, the coordinates (x'1, y'1, z'1) of the machining reference point, which is the coordinate system in these three-dimensional measuring machines 2, are used. To N

The work coordinate system of the NC processing machine 1 (X ", Y",
In the conversion to Z "), the value of the center of the master pallet in the NC processing machine 1 can be used as fixed data, but in order to perform processing with higher accuracy, the value measured during machine adjustment should be corrected. Since it is preferable to use the multiplied value, the following operation in the data conversion unit 44 will be described with reference to the data conversion in consideration of the above correction.

The work coordinate system of the NC processing machine 1 (X ", Y",
The origin coordinates of Z ") are as follows: Coordinate value of master pallet reference point when NC processing machine 1 is installed: X0, Y0, Z0 Value for correcting pallet center: ΔX, ΔY, Δ Coordinates of machining reference point of Z workpiece: x'1, y'1, z'1 Operation 1: (X0 + ΔX, Y0 + ΔY, Z0 + ΔZ) is calculated, and the master pallet in NC machine 1 after correction Set to (0, 0, 0) of the reference coordinate system (X ', Y', Z ') Operation 2: The point obtained by the above operation 1 is the work coordinate system (X ", of the NC processing machine 1). (-X'1, -y'1, Y ", Z")
-Z'1).
