The above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments.

Referring to Figures 1 and 2, the present invention is applied to a preferred embodiment of a controller for a multi-spindle processing machine, the processing machine 6 including a first spindle corresponding to a first coordinate system 81 and movable in a first direction 71 61.

The first direction 71, the third direction 73 and the fourth direction 74 together constitute the first coordinate system 81, and the second direction 72, the third direction 73 and the fourth direction 74 together constitute the second coordinate system 82. The relationship of the second coordinate system 82 relative to the first coordinate system 81 is represented by a landmark vector 83.

The first spindle 61 has a first cutter 611 having a second cutter 621 representing a machined end 622 of the second cutter 621 corresponding to a second of the second coordinate system 82. The reference coordinate corresponds to the relationship of the machining end 612 of the first tool 611 to a first reference coordinate in the first coordinate system 82. In this embodiment, the first cutter 611 and the second cutter 621 are grinding wheels of different diameters.

The controller applied to the multi-spindle processing machine includes an interpreting unit 2, a label processing unit 3, and a motion control unit 4. In this embodiment, the interpreting unit 2 and the coordinate processing unit 3 are implemented by a software program.

The interpreting unit 2 is configured to interpret a set of processing instructions 20 to generate a machining command 21. In the embodiment, the processing instruction set 20 is a software program instruction.

The coordinate unit parameter 22 corresponding to the coordinate vector 83, a first reference coordinate information 23 corresponding to the first reference coordinate, and a second reference coordinate information 24 corresponding to the second reference coordinate are pre-stored in the interpreting unit 2. . In this embodiment, the coordinate vector parameter 22 is in the form of a matrix.

The machining command includes a spindle number information corresponding to one of the first spindle 61 and the second spindle 62, and a machining path parameter.

The coordinate processing unit 3 receives the machining command 21, and when the spindle serial number information corresponds to the first spindle 61, the coordinate processing unit 3 outputs the spindle serial number information and a reference processing path parameter identical to the processing path parameter, when When the spindle serial number information corresponds to the second spindle 62, the coordinate processing unit 3 outputs the spindle serial number information and a conversion processing path parameter, and the conversion processing path parameter is the coordinate vector parameter according to the processing path parameter and the corresponding coordinate vector 83. 22 after the operation is obtained.

In the embodiment, the reference processing path parameter is the final moving coordinate of the first tool 611 in the first coordinate system 81, and the conversion processing path parameter is the second tool 621 in the second coordinate system 82. Finally, when the coordinate number information corresponds to the second spindle 62, the processing path parameter and the position in the physical space represented by the conversion processing path are substantially the same.

After receiving the spindle serial number information and the reference processing path parameter, the motion control unit 4 generates a first signal 41 for driving the first spindle 61 to be processed according to the reference processing path parameter, and receiving the spindle serial number information and the conversion processing. After the path parameter, a second signal 42 is generated that drives the second spindle 62 to process according to the conversion processing path parameter.

The first signal 41 can drive the first spindle 61, the first horizontal drive shaft 63 and the second horizontal drive shaft 64 to move the first cutter 611 of the first spindle 61 according to the first reference coordinate information. And processing the reference processing path parameter, wherein the second signal 42 can drive the second spindle 62, the first horizontal driving shaft 63 and the second horizontal driving shaft 64 to move to drive the second spindle 62 The tool 621 performs machining based on the second reference coordinate information and the reference machining path parameter.

For example, the processing of the first tool 611 and the second tool 621 is performed on a workpiece to be processed. First, a machining sequence is first written in the machining instruction set 20, and the machining sequence is to first make the first spindle 61. Moving in the first coordinate system 81, and interlocking the first tool 611 from point A to point B in the figure, and then moving the second spindle 62 in the second coordinate system 82, and interlocking the second The tool 621 moves from point B to point C in the drawing, since the first spindle 61 can only move along the first coordinate system 81, and the second spindle 62 can only move along the second coordinate system 82, In short, the processing sequence actually generates four actions for moving the first spindle 61 along the first coordinate system 81 to point A, and moving the first spindle 61 along the first coordinate system 81 to Point B, the second spindle 62 is moved along the second coordinate system 82 to point B, and the second spindle 62 is moved along the second coordinate system 82 to point C. It should be noted that the processing sequence may of course cause the mutual interference of the first main shaft 61 and the second main shaft 62, and before moving one of the main shafts, the other main shaft that may cause interference is removed first. This is easily understood by those of ordinary skill in the art to which the present invention pertains, and therefore, such an action will not be described below.

In use, the interpreting unit 2 decodes the four machining commands 21 corresponding to the four actions according to the machining instruction set 20, and in the first machining command 21, moves the first spindle 61 to the phase. Corresponding to the final moving coordinate of the processing path parameter, the coordinate processing unit 3 generates a reference processing path parameter identical to the processing path parameter, and causes the motion control unit 4 to generate the first signal 41, and the first signal 41 at this time The first tool 611, which can be used to drive the first spindle 61, is moved along the first coordinate system 81 to a point A corresponding to the reference machining path parameter.

The position of point B, in the process, the first tool 611 will process the workpiece 5 to be processed.

In the third machining command 21, the second spindle 62 is moved to the final moving coordinate of the corresponding machining path parameter, and the coordinate processing unit 3 is caused to have the coordinate vector of the corresponding coordinate vector 83 according to the processing path parameter. The conversion processing path parameter is obtained after the parameter operation, that is, the final moving coordinate corresponding to the first coordinate system 81 is converted into a final moving coordinate corresponding to the second coordinate system 82, and the new final moving coordinate is The second spindle 62 is in a target position to be moved in the second coordinate system 82, and the motion control unit 4 generates the second signal 42. At this time, the second signal 42 can be used to drive the second spindle 62. The second tool 621 is moved along the second coordinate system 82 to a position B corresponding to the reference machining path parameter.

In the fourth machining command 21, the second spindle 62 is moved to the final moving coordinate of the corresponding machining path parameter, and the coordinate processing unit 3 causes the coordinate vector according to the machining path parameter and the corresponding coordinate vector 83. The conversion processing path parameter is obtained after the parameter operation, that is, the final moving coordinate corresponding to the first coordinate system 81 is converted into a final moving coordinate corresponding to the second coordinate system 82, and the new final moving coordinate is The second spindle 62 is in a target position to be moved in the second coordinate system 82, and the motion control unit 4 generates the second signal 42.

One of them can be applied to the processing of the corresponding one of the first main shaft 61 and the second main shaft 62, and the processing accepted by the present invention is compared with the controller of the existing multi-spindle processing machine. The instruction set 20 can be relative to the first coordinate system 81, and can avoid a large number of coordinate conversion work on different spindles before the processing instruction set 20 is generated, which can greatly reduce the time cost before production, so the actual cost can be achieved. The purpose of the invention.
