Inter-element calculations are performed, for example, in the following procedure. First, the user uses a three-dimensional measuring machine to measure a plurality of elements (for example, points, straight lines, planes, circles, etc.) of the workpiece. Here, the measurement of an element may be performed multiple times for one element. Thereby, the measurement results (for example, position, coordinates, dimensions, etc.) of the element measured using the three-dimensional measuring machine are stored.

Next, the user selects an item indicating the type of calculation or the target of evaluation in the inter-element calculation from the menu displayed on the display screen. Here, inter-element calculation refers to calculating another mechanical index (parameter) by combining a plurality of elements that have already been stored. Inter-element calculation items include, for example, intersecting elements (intersecting points, intersecting lines, etc.), symmetrical elements (midpoints, symmetrical lines, symmetrical planes, etc.), shortest/longest distance, distance between two points, coordinate difference between two points , squareness between two planes and between a straight line and a plane, etc. The user selects an element to be used for inter-element calculation from the list of measurement results regarding a plurality of elements displayed on the display screen. As a result, the inter-element calculation is performed for the selected item using the measurement result of the selected element, and the result of the inter-element calculation is displayed on the display screen.

As described above, in inter-element calculations, it is necessary to select items and elements each time inter-element calculations are performed. Specifically, each time calculation between elements is performed, an operation is performed to transition the screen among a plurality of operation screens including a display screen for element measurement results, an item selection screen, and an element selection screen. . Therefore, there is a problem that the number of screen transitions increases and the operation becomes complicated.

For example, when measuring a plurality of workpieces having the same shape, the operation procedure for selecting items in inter-element calculation and selecting the type and number of elements can be almost the same. In this case, the user repeats the same operation procedure every time one workpiece is measured. Therefore, the same operation procedure is repeated in correspondence with the number of workpieces to be measured.

Also, depending on the user or the type of work to be measured, there are cases where the items, the types and the number of elements in the inter-element calculation are determined in advance. In this case, the user repeats the same operation for item selection and element selection each time the workpiece is measured.

Even in the above case, the operation becomes troublesome if items and elements are selected each time one workpiece is measured and inter-element calculations are performed. Furthermore, since it takes time to repeat the same operation procedure, there is a problem that the throughput of measurement of workpieces is lowered. If the throughput of measurement and calculation between elements for verifying the machining accuracy of the work is lowered, there is a problem that the productivity of the work is lowered.

The present invention has been made in view of such circumstances, and provides a three-dimensional measurement result processing method, processing apparatus, and three-dimensional measurement that are capable of simplifying the operation procedure when measuring a workpiece and performing calculations between elements. The purpose is to provide

As means for fixing the workpiece to the surface of the surface plate 18, for example, a clamping mechanism can be used.

A pair of columns (struts) 16 extending upward (+z direction) in the drawing from the surface of the surface plate 18 is attached to the surface plate 18 . A beam 14 spans over the upper end of the column 16 (the end on the +z side). The pair of columns 16 can move synchronously in the y direction on the surface plate 18, and the beam 14 can move in the y direction while being parallel to the x direction. A motor can be used as a driving means for moving the column 16 with respect to the platen 18 . Note that the pair of columns 16 may be connected on the lower surface side of the surface plate 18 .

Attached to the beam 14 is a head 12 extending in the z-direction. The head 12 is movable along the length direction (x direction) of the beam 14 . A motor can be used as the driving means for moving the head 12 relative to the beam 14 .

A probe 22 is attached to the lower end (-z side end) of the head 12 so as to be movable in the vertical direction (z direction) in the figure. A motor can be used as a driving means for moving the probe 22 in the vertical direction.

The measuring machine main body 10 includes a travel amount measuring section (for example, a linear encoder, not shown) for measuring the respective travel amounts of the column 16, the head 12 and the probe 22. FIG.

The probe 22 includes a highly rigid shaft-shaped member (stylus 24). As the material of the stylus 24, for example, super hard alloy, titanium, stainless steel, ceramics, carbon fiber, etc. can be used.

[Specific example of measurement menu]
Next, a specific example of a measurement menu for performing workpiece measurement and inter-element calculation in the three-dimensional measuring machine 1 according to this embodiment will be described.

An example of measuring a plurality of elements of the workpiece W1 shown in FIG. 2 will be described below. FIG. 2 is a partial plan view showing a workpiece to be measured. In the example shown in FIG. 2, three circles C1 to C3 are shown as elements on the surface S1 (plane) of the workpiece W1.

3 to 10 are diagrams showing examples of measurement menus (GUI) generated by the inter-element calculation program. Buttons shown in each measurement menu may be touch-operable by a touch panel as the operation device 104, or may be associated with buttons (for example, function keys) of a keyboard as the operation device 104 or mouse gestures. .

(at first measurement)
First, the screen transition at the time of initial measurement in the three-dimensional measuring machine 1 will be described.

FIG. 3 shows a menu for selecting elements when performing three-dimensional measurements. In this embodiment, a code (letter, number, or a combination thereof) is assigned to identify the type of element, and in the inter-element calculation program, each element using the code assigned to the type of element may be calculated and displayed. For example, assigning a to a point, b to a straight line, c to a circle, d to a partial circle, e to a sphere, f to a plane, g to a cylinder, and h to a cone, the processing unit 102 assigns element types by these codes. You may recognize it.

When the probing button (see FIG. 3) is operated using the operating device 104 of the computer 100, the processing device 102 transmits a probing signal to the main body 10 of the measuring instrument. When receiving the probing signal, the measuring machine body 10 uses the probe 22 to start measuring the elements of the workpiece W1. As a result, preparatory processing for measurement such as setting of measurement coordinates (hereinafter referred to as XYZ three-dimensional rectangular coordinates (see FIG. 2)) for the workpiece W1 is performed.

The user operates the measuring instrument main body 10 to measure the workpiece W1 placed and fixed on the surface plate 18 . The measurement result of work W1 is transmitted to computer 100 via controller 110 .

The processing device 102 (measurement result acquisition unit) acquires (receives) the results of the elements measured by the three-dimensional measuring machine 1 and stores them in the storage device 106 as measurement result data. The processing device 102 also causes the display device 108 to display the measurement result data. As a result, the measurement result for each element of the workpiece W1 is displayed on the display screen of the display device 108, as shown in the measurement result display screen of FIG.

In the example shown in FIG. 4, as the element measurement results, the point measurement result PNT1, the straight line measurement results LIN1, LIN2 and LIN3, the plane measurement result PLN1, and the circle measurement results CIR1, CIR2 and CIR3 are illustrated. In the example shown in FIG. 4, coordinates of representative points corresponding to each measurement result are shown.

In the example shown in FIG. 4, straight lines LIN1, LIN2, and LIN3 indicate measurement results obtained by measuring different straight lines once. CIR1, CIR2 and CIR3 in FIG. 4 indicate the measurement results obtained by measuring the coordinates of the centers of the circles C1, C2 and C3 respectively shown in FIG. 2 once.

Note that it is conceivable that the same type of element is measured multiple times. For example, when the circle C1 shown in FIG. 2 is measured three times, the measurement results of the circle C1 may be displayed as CIR1, CIR2 and CIR3. Further, when the circle C1 is measured once and the circle C2 is measured twice, the measurement result of the circle C1 may be displayed as CIR1, and the measurement results of the circle C2 as CIR2 and CIR3. In this case, an element that has been measured multiple times may be given a display indicating that it is the measurement result of the same element, for example, an identifier such as a circle for identifying the element.

Next, when the user uses the operation device 104 to input an instruction to end the measurement (terminate), the processing device 102 transmits a terminate signal to the measuring instrument main body 10 . When receiving the terminate signal, the measuring machine body 10 ends the measurement of the workpiece W1 and performs post-processing such as storage of the measurement results.

Next, items are selected in FIG. 4 (measurement result display screen) and FIG. 5 (item selection screen). Among the buttons on the left side of FIGS. 4 and 5, "create element" performs calculation of new elements (intersection element, symmetrical element, measurement point recall, recalculation, etc.) using the measurement results of a plurality of elements, for example. It is a button for "Evaluate" is a button for evaluating, for example, the distance between two points, or the perpendicularity between two straight lines, planes, or a straight line and a plane.

When the element creation button is operated in FIG. 4 (measurement result display screen), the screen shifts to the item selection screen regarding element creation shown in FIG. An example in which the measurement point recall is selected in FIG. 5 will be described below. In FIG. 5, the selected element creation button and measurement point recall button are shown in a different color than the unselected buttons.

When the measurement point recall button is operated in FIG. 5 (item selection screen), the element selection screen for measurement point recall shown in FIG. 6 is displayed. On the element selection screen, it is possible to select the element to be used in recalling the measurement point while operating the scroll bar shown on the right side of the figure. In the example shown in FIG. 6, three circle measurements have been selected and shown in a different color than the unselected elements. In addition, in the example shown in FIG. 6, the selected measurement results are displayed with numbers according to the order of selection.

Next, when the next button is operated after selecting an element in FIG. 6, the screen transitions to FIG. 7, and the result of calculation between elements is displayed. The processor 102 (inter-element calculator) stores the measurement results CIR1, CIR2 and CIR3 of the elements selected in FIG. Also, the calculation results of the elements created from the measurement results CIR1, CIR2, and CIR3, for example, the data of the circle C10 (see FIG. 2) passing through the center of each circle, are stored in the storage device 106. FIG.

(For second and subsequent measurements)
Next, screen transitions during the second and subsequent measurements in the three-dimensional measuring machine 1 will be described.

From the start to the end of probing, the operation menu transitions according to the same operation as in the initial measurement (see FIGS. 3 and 4).

When the probing ends, the processing device 102 (display control unit) causes the display device 108 to display a selection candidate display screen D12 on the measurement result display screen, as shown in FIG. The selection candidate display screen D12 displays operation members (for example, buttons) corresponding to items and elements selected during past measurements. The processing device 102 (accepting unit) accepts selection of items and elements for calculation between elements via this operation member. In the example shown in FIG. 8, a measurement point recall button selected at the initial measurement is displayed. In the measurement result display area D10, three circle measurement results are automatically selected according to the type and number of elements used in the first measurement point recall. In FIG. 8, the color change of the circle measurements CIR1, CIR2 and CIR3 shows that these measurements were automatically selected.

When the user recalls the measurement points using the measurement results of the three circles, as in the first measurement, the user operates the measurement point recall button displayed on the selection candidate display screen D12 to recall the measurement points. A recall can be performed.

It should be noted that the buttons displayed on the selection candidate display screen D12 may display information (e.g., symbols, etc.) indicating the type and number of elements (e.g., three circles) required for inter-element calculations. good.

When the three-dimensional measuring machine 1 repeatedly performs measurements and inter-element calculations, as shown in FIG. 9, a plurality of buttons indicating items of inter-element calculations that have been performed in the three-dimensional measuring machine 1 in the past are displayed.

In the example shown in FIG. 9, buttons for the distance and squareness between two points are shown in addition to the measurement point recall. Then, in the measurement result display area D10, the measurement result of the element is automatically selected according to the type and number of elements used in the inter-element calculation corresponding to each button. The buttons on the selection candidate display screen D12 and the automatically selected measurement results are displayed in the same color. In the example shown in FIG. 9, the two-point distance button and the two-point measurement results (PNT1 and PNT2) are shown in dark gray, the squareness button and the straight line measurement result (LIN1) and the plane Measurement results (PLN2) are shown in light gray.

Here, if the type and number of elements used in the inter-element calculation item displayed on the selection candidate display screen D12 and the type and number of elements displayed in the measurement result display area D10 are different, the measurement result is automatically displayed. may not be automatically selected.

Further, when the number of elements displayed in the measurement result display area D10 is larger than the number of elements used for the inter-element calculation item displayed on the selection candidate display screen D12, the element candidate to be selected is highlighted. may be made. For example, when there are three or more point measurement results, all point measurement results may be highlighted when a distance button between two points is pressed. This allows the user to easily select the measurement results required for inter-element calculations.

Further, when the number of elements displayed in the measurement result display area D10 is smaller than the number of elements used for the item of calculation between elements displayed on the selection candidate display screen D12, the measurement results of the elements are insufficient. A message may be displayed on the display device 108 notifying the presence of the element and prompting the user to make additional measurements, and the inter-element calculation may be terminated.

In addition, the processing device 102, based on the elapsed time since the button of the element used for the item of calculation between elements displayed on the selection candidate display screen D12 was selected and the number of selection operations (selection frequency), You may make it decide whether to display a button. Alternatively, the importance of selection candidates may be calculated based on both the elapsed time and the number of selections, and the selection candidates to be displayed on the selection candidate display screen D12 may be selected according to the calculated importance. The example shown in FIG. 10 shows an example in which the square button is deleted by the selection function of this button.

In the selection candidate display screen D12, the buttons indicating the items of calculation between elements may be resized so as to fit in one screen, for example, or may be scrolled by providing a scroll bar in order to maintain listability. good too. Further, in the selection candidate display screen D12, the buttons indicating items of calculation between elements may be sorted, for example, according to the frequency of use or the latest date and time of use.

The three-dimensional measuring machine 1 according to the present embodiment and the method for processing the three-dimensional measurement results thereof are not limited to the above-described measurement point recall and the like, and calculations between elements other than the above, such as element creation and measurement using the measurement results, are performed. It can be used for evaluation of results. Element creation includes, for example, intersecting elements, symmetrical elements, measuring point recall, recalculation, measurement plane projection, inclined plane projection, rotation projection, maximum and minimum points, calculation of cut center circle and perpendicular line, etc. It is possible to In addition, the evaluation includes the distance between two points, the coordinate difference between two points, the shortest and longest distance, the degree of position, the concentricity, the coaxiality (protrusion tolerance), the parallelism (protrusion tolerance), and the perpendicularity (protrusion tolerance). The present invention can also be applied to the evaluation of

[Processing flow of measurement and calculation between elements]
Next, processing of measurement and calculation between elements will be described with reference to FIGS. 11 and 12. FIG. FIG. 11 is a flow chart showing the flow of processing for measurement and calculation between elements.

(at first measurement)
First, the element measurement of the workpiece is performed by the measuring machine main body 10 (step S10). When the element measurement ends (terminates), the processing device 102 receives the result of the element measured by the three-dimensional measuring machine 1 and stores it in the storage device 106 as measurement result data. At the time of the first measurement, there are no selection candidates (No in step S12), so the process proceeds to step S14.

Next, the processing device 102 causes the display device 108 to display the measurement result data (see FIG. 4). Then, the processing device 102 causes the display device 108 to display an item selection screen (see FIG. 5), and receives an item selection operation from the user (step S14).

Next, when receiving an item selection operation from the user, the processing device 102 displays an element selection screen (see FIG. 6) on the display device 108, and receives an element selection operation from the user (step S16).

Next, the processing device 102 performs inter-element calculations according to the selection results of the items and elements in steps S14 and S16, and evaluates the results (for example, the results of element creation, or squareness etc. based on the inter-element calculations). result) is displayed on the display device 108 (step S26). Then, the processing device 102 causes the storage device 106 to store the result of the inter-element calculation (step S28).

(For second and subsequent measurements)
Next, the second and subsequent measurements will be described.

First, the element measurement of the workpiece is performed by the measuring machine main body 10 (step S10). When the element measurement ends (terminates), the processing device 102 receives the result of the element measured by the three-dimensional measuring machine 1 and stores it in the storage device 106 as measurement result data.

Next, the processing device 102 causes the display device 108 to display the selection candidate display screen D12 (see FIGS. 8 to 10) (step S18), and receives a selection candidate selection operation from the user (step S20). Selection of the displayed selection candidates will be described later with reference to FIG. 12 .

When the number of elements measured in step S10 is greater than the number of elements used in the inter-element calculation item selected in step S20 (No in step S22 and No in step S24), the processing device 102 The element selection screen (see FIG. 6) is displayed on the display device 108, and element selection is accepted (step S24).

On the other hand, if the number of elements used in the inter-element calculation item selected in step S20 matches the number of elements measured in step S10 (Yes in step S22), the element selection screen in step S24 is skipped. Then, the process proceeds to step S26.

Further, when the number of elements measured in step S10 is larger than the number of elements used in the inter-element calculation item selected in step S20 (No in step S22 and Yes in step S24), element measurement A message is displayed on the display device 108 notifying that the results are insufficient and prompting additional measurements, and the inter-element calculation is terminated.

Next, the processing device 102 performs inter-element calculations according to the selection results of the items and elements in steps S14 and S16, and causes the display device 108 to display the results (step S26). Then, the processing device 102 causes the storage device 106 to store the result of the inter-element calculation (step S28).

(Selection candidate display screen)
Next, selection of selection candidates displayed in step S18 will be described with reference to FIG. FIG. 12 is a flowchart showing the flow of processing for generating a selection candidate display screen.

When generating the selection candidate display screen D12, the processing device 102 first acquires the history of the items of the inter-element calculation selected in the past and the types and numbers of the elements from the storage device 106 as selection candidates (step S180).

Next, the processing device 102 acquires the latest selection date and time of each selection candidate (step S182), and selects a selection candidate to be displayed on the selection candidate display screen D12 based on the latest selection date and time of each selection candidate (step S182). step S184). In step S184, the processing device 102 selects, for example, selection candidates whose elapsed time from the latest selection date and time of each selection candidate is within a predetermined time period as selection candidates to be displayed on the selection candidate display screen D12. Then, the processing device 102 displays the selection candidate selected in step S184 on the selection candidate display screen D12 (step S186).

In the present embodiment, selection candidates to be displayed on the selection candidate display screen D12 are selected according to the elapsed time from the latest selection date and time, but the present invention is not limited to this. For example, the selection candidates to be displayed on the selection candidate display screen D12 may be selected according to the number of selections (selection frequency) of the selection candidates. Alternatively, the importance of selection candidates may be calculated based on both the elapsed time and the number of selections, and the selection candidates to be displayed on the selection candidate display screen D12 may be selected according to the calculated importance.

Also, the order of display on the selection candidate display screen D12 may be changed according to the elapsed time, the number of selections, or the degree of importance. For example, on the selection candidate display screen D12, the selection candidate buttons may be rearranged in order of short elapsed time, high number of selections, or high importance.
