Abstract

PURPOSE:To dispense with preparation of a troublesome plane movement program by instituting a moving route so as to connect in order the instituted initial planes corresponding to an instituted index plane and a working plane, and moving the blade edge of a tool along the route. CONSTITUTION:Initial planes ILP are respectively instituted with a space by a prescribed distance L on a plurality of working planes 16a - 16e of a work 16 to be worked with a five planes working machine, and an index plane IXP is instituted separating upward by a prescribed distance from the initial plane ILPu of the upper working plane 16a. When a tool mounting means performs plane moving, the instituted initial planes ILP corresponding to worked planes 16a - 16e completed directly before, the index plane IXP, and instituted initial planes ILP corresponding to working planes 16a - 16e to be worked herefrom, are connected in order so as to institute a moving route PAS, and the blade edge 39a of a tool 39 is moved along this. Thus, preparation of the troublesome plane movement program becomes unnecessary and the miss accompanied with preparation can be dissolved.

In addition, in the same machining process PRO, the numbers stored in the rEFR-No and J digits define at which position on each machining surface of the workpiece 16 the origin of the program coordinate system is set. The basic coordinate number is FN○, and the basic coordinate FRM corresponding to the basic coordinate number FN○ is stored in the data memory 17. Basic coordinates FR not stored in data memory 17

rFRM-(The number stored in the IJ digit is the coordinate setting angle that indicates how much the machine coordinate system is rotated around the program coordinate system or the y-axis of the program coordinate system.

In this way, when the five-time Niprogram program FPR is stored in the Niprogram program memory 9, the palette changer 2
The work pallet 25 on which the workpiece 1G to be machined is mounted is placed on the table 23, and in this state, the operator outputs a machining start command to the main control unit 2 via the input unit 5.

Then, the main control unit 2 sends 5 messages to the program analysis unit 10.
Commands analysis of the recursive program FPR.

In response to this, the program analysis unit 10 refers to the "5-face machining" stored as the machining instruction command PK in the "unit" digit of the 5-face machining program FPR, and determines that the machining to be performed from now on will be performed on the 5 faces of the workpiece 16. It recognizes that it is processing, reads out the processing program UPP corresponding to the five-sided processing from the system t1 block processing program UPP, and executes the five-time processing program F P R based on the two-knit processing program UPP. Perform analysis operations and subsequent processing operations.

That is, the processing program UPP shown in FIG.
In step S1, the 5-times Niprogram program FPR stored in the Cannibal program memory 9 is read out, and each processed data DAT stored in the read five-sided Niprogram program FPR is read.

Next, based on the read machining data DAT, the rsNo in the full-jaw two-step PR, the sequence number SNO stored in the J digit, and the machining surface definition command PF stored in the "machining surface" digit, A flag table FT is created that serves as an index for surface movement of the adapter head 35 in five-face machining, and the created flag table FT is stored in the flag table memory 20.

This flag table FT has, for example, 5 flags as shown in FIG.
The flag step FS (F
Sl, FS2, FS3, etc.), and each flag step FS includes a surface movement number TN○ indicating the execution order of surface movement and a flag F corresponding to the surface movement number TNO.
LG is stored in rTNo, J and "F" digits, respectively. That is, rTNo, the first flag step FS where the surface movement number TNO stored in the J digit is "1"
1 corresponds to the first press step PR□ in the machining process PRO of the five-sided apron frame FPR shown in FIG. 11, and the flag FLG stored in the "F" digit in the first flag step FS. is set based on the machining surface definition command PF stored in the "machining surface" digit in the first machining step PR□, and indicates the surface movement coordinate when executing the first machining step PR1. (more on that later). Also, rTN
The second flag step FS2 in which the surface movement number TN○ stored in the o and J digits is "2" is the first flag step FS2 in the machining process PR○ of the 5-time Niprogram FPR shown in FIG.
The flag FLG stored in the "F" digit in the second flag step FS2 corresponds to the [processing] step in the first and second processing steps PR1 and PR2. It is set based on the machining surface definition commands PF and PF stored in the "plane" digit, and indicates the surface movement coordinates when executing the second machining step PR2. Furthermore, rTNo, the third and fourth flannel steps FS3. in which the surface movement number TN○ stored in the J digit are "3", "4", etc. FS, etc. have the same configuration as the second flag step FS2 described above. That is,
rT No.

are the n-1st and n-th steps P in the processing process PRO of the 5-times Kniprogram FPR shown in the first soil map.
The flag FLG stored in the "F" digit in the first flag step FS, , corresponds to the n-1st and first step PR,
It is set based on the machining surface definition commands PF and PF stored in the "machining surface" digit in PRo, and indicates the surface movement coordinates when executing the first machining step PR. be.

For example, the flag table FT shown in FIG. 13 is created based on the 5-time addition program FPR shown in FIG. The first flag step FS□ where TN○ is “1” is the 5-time addition program F shown in FIG.
This corresponds to the first addition step PR□ of PR.

That is, since the "top surface" is stored in the "machining surface" digit of the first machining aesthetic knob PR□ as the machining surface definition command PF, the "F" digit of the first flag step FS is In the flag table FT, "FU" meaning the upper surface 16a of the workpiece 16 is stored as a flag FLG. Therefore, the first flag step FS moves the adapter spatulas 1 to 35 to the workpiece 1G when performing the first surface movement in the five-face machining, that is, the machining defined in the first two-step PR. This means moving it to the upper surface 16a.

Further, the second flag step FS2 in which the surface movement number TN○ stored in the digit rT"No and J of the flag table FT shown in FIG. The first and second Canadian steps PR, PH1
0, and the "machining surface" digit of the first and second machining steps PR□ and PR7 has a machining surface definition command P.
Since "top surface" and "0°" are stored as F, respectively, the "F" digit of the first flag step FS contains the information from the top surface 16a of the workpiece 16 to the 06 surface 16b in the flag table FT. 'F u-+F which means movement
o J is stored as a flag FLG. Therefore, the second flag step FS2 is the second flag step FS2 in the five-sided machining.
When the machining step PR to be executed moves from the first machining step PR□ to the second machining step PR2, the adapter head 35 is moved to the upper surface of the workpiece 16.

In this way, the unit processing program UP shown in FIG.
In Step S1 of P, when the flag table FT corresponding to the 5-time Niprogram program FPR is created and stored in the flag table memory 20, the first step PR of the 5-time Niprogram program FPR shown in FIG. In order to perform the previously defined machining, that is, the machining corresponding to the machining program number PNOrl 11J on the upper surface 16a of the workpiece 16, the process proceeds to step S2, in which the machining that will be performed from now on, that is, the machining defined in the first machining step PR machining, is executed. It is determined whether or not this is the first machining of the workpiece 16. To do this, it is determined whether the sequence number SN○ stored in the rsNo, J digit of the Canadian step PR is "1", and if the sequence number SN○ is determined to be "1", then is determined to be the machining to be performed from now on or the first machining for the workpiece 16, and if it is determined that the sequence number SN○ is not "1",
It is determined that the machining to be performed from now on is not the first machining for the workpiece 16.

In this way, as a result of the determination based on the flag table F T in step S2, the processing to be performed from now on, that is, the processing defined by the first machining esthetic knob PR, has a sequence number SNO of "1", so It is determined that this is the first machining, and the process proceeds to step S3, in which the head number HNO is stored in the digit J of the 22-no-1 designated process UDP of the 5-time Niprogram FPR shown in FIG. Based on "9", the adapter head 35 is replaced, and the adapter head 35 corresponding to the five-sided machining to be performed from now on is attached to the head 29.

This replacement operation of the adapter head 35 is performed in the following steps. That is, as shown in FIG. 2, the drive motor 33d of the head transfer device 33 is driven to drive the carrier 33b along the guide rails 33a, 33a in the directions of arrows A and B via the feed screw 33c.

In this state, the transfer device 33h of the head mounting section 33e is driven to transfer the adapter head 35 in the head storage magazine 31 to the head mounting section 33e of the carrier 33b.
Transferred to.

In this way, one head mounting portion 33e of the carrier 33b
When the adapter head 35 to be replaced has been transferred, the other head mounting section 33f is left vacant on the carrier 33.
b is moved in the direction of the arrow to position the vacant head mounting section 33f at a predetermined head exchange position as shown in FIG. In this state, the saddle 22 is moved in the direction of arrow C in FIG. 2, and as shown in FIG. Position. Next, the head 29 is moved in the direction of arrow F, and as shown in FIGS. 6 to 8, the adapter head 1 that was previously attached to the head 29 is
35 is placed on the vacant head mounting section 33f. Next, the head 29 is raised in the direction of arrow E, and the carrier 33b is moved a predetermined distance in the direction of arrow B, so that the head 29 of the adapter head 35 is mounted on the removed head 29 and the head mounting portion 33e of the carrier 33b. The adapter heads 35 to be attached are placed facing each other as shown in FIG. In this state, as shown in FIGS. 9 and 10, the head 29 is moved in the direction of arrow F, and the adapter spatula 1 is attached to the head 29.

In this way, in step S3, when the adapter head 35 corresponding to the five-sided machining to be performed from now on is attached to the head 29, the process proceeds to step S4, in which the upper surface 16 of the workpiece 16 is attached.
Automatic tool exchange is performed prior to the machining operation for a.

The tool 39 to be used for machining compatible with l'liJ is transferred from the tool machine 37 to the adapter/tool changer 36.
After the tool 39 is attached to the tool gripping portion 35d or 35e of the bed 35, the adapter head 35 with the tool 39 attached thereto is positioned at a predetermined standby position.

In this way, in step S4, when the tool 39 to be used for the upper surface 16a of the workpiece 16, which is the first machining surface, is attached to the adapter head 35, the process proceeds to step S5, and the main control unit 2 shown in FIG. is the initial surface setting section",
9, the setting of the initial painter LP, which is the path of the cutting edge 39a of the tool 39 when the adapter head 35 moves in the five-sided machining of the workpiece 16, is commanded. In response to this, the initial surface setting unit 19 sets the rEF in the machining process PR○ of the 5-time Niprogram FPR shown in FIG.

Initial plane iLP is set at a position separated by a predetermined distance in the +Z-axis direction from each machined surface of [position, that is, workpiece] 6, in a manner that surrounds the machined surface.

That is, in the case of the rectangular parallelepiped-shaped work 16 shown in FIG. 17, the initial surface IL corresponds to the upper surface 16a of the work 16.
1'u corresponds to the O'' surface 16b of the workpiece 16, and the initial surface ILPo corresponds to the 90'' surface 16c, and the initial surface IL? 1, and the initial plane ILP2 corresponds to the 180° plane 16d.

An initial plane ILP3 is set corresponding to the 270° plane 16e. Note that when the machined surface of the workpiece 16 has irregularities, the initial surface ILP is set at a position separated by a distance in the +Z-axis direction from the maximum protrusion portion of the machined surface. Therefore, regardless of the shape of the machined surface of the workpiece 16, the initial plane ILP is set at a distance of 14L or more from any part of the machined surface. When the tool 39a moves along the set initial plane

The position of the cutting edge of the tool 39 is calculated based on the offset l-amount, and five-sided machining block diagram FPR is executed based on the calculated cutting edge position.

In this way, in step S6, after the spatula 1 to correction amounts have been calculated and the cutting edge position of the tool 39 has been calculated,

In step S24, the adapter head 35 is rotated in the direction of arrow M or N until it faces the direction facing the current machining surface while the cutting edge 39a of the tool 39 is held within the index plane IXP. (However, in the flag table FT shown in FIG. 13, the flag FLG is "F, J" indicating movement to the upper surface 16a of the workpiece 16, so the tool 3

In this manner, in step S24, when the adapter head 35 has turned together with the tool 39 to a predetermined angular position in the direction of the arrow M or N, the process proceeds to step S25, in which the tool 39 is rotated based on the set movement path PAS and the drive shaft. The cutting edge 39a is positioned from the reference position P2 on the index plane IXP to the reference position P5 on the initial plane ILP.

For example, if the flag FLG is the 270° plane 16e of the workpiece 16,
If it is determined that it is "F3" indicating movement to , and the corresponding movement path PAS and drive axis are set,
The main control section 2 outputs a movement command to the table control section 11, saddle control section 12, and head control section 13 to move the tool 39 to the passing point P4 on the index plane IXP. In response to this, the table control section 11 moves the table 23 in the X-axis direction via the drive motor 14, and the saddle control section 12 moves the head 29 in the Y-axis direction via the drive motor 15. As shown in FIG. 17, the cutting edge 39a of the tool 39 is moved from the reference position P2 along the set moving path PAS, that is, along the shortest path, on the index plane IXP to the passing point P4.
