The "M99π" of the formula (14) is the end command of the macro program. The variable values defined by the formulas (11) to (13) will vary with the size of the edge finder used and the cutting center machine used. The number of tools is different, and changes will be made. When the program of the "M200" instruction is completed, the follow-up method can be performed.

Page 9 518264 V. Description of the invention (7) ---- The operation of the program reference point on the workpiece. The workpiece processed in this embodiment is shown in the fourth figure (20), and the workpiece (20) has two reference edges (22) (24) that have been previously ground and are adjacent to each other. The preferred embodiment is to place the workpiece (20) in quadrant coordinates. 2. The operator also makes the mode selection switch in Mj) I mode. Refer to the working coordinate to qffset to determine which coordinate system the workpiece is in. In this embodiment, the workpiece coordinate system 3: g 56 is used as an example. Press PROGRAM function key repeatedly and enter G56.

After that, the main axis is manually operated, and the edge seeker is used to find the coordinates of the first reference edge (22) of the workpiece, as shown in point a in the fourth figure. The first reference is completed for the small diameter portion (16) of the edge seeker. The state of the edge (2 2); After the coordinates of the first reference edge are obtained, in the MDI mode, enter the "G1 〇〇" command; move the main axis, and guess the coordinates of the second reference edge (2 4), such as Point b in the fourth figure, after measuring the coordinates of the second reference edge (24), also enter the "G100" command in the MDI mode; after measuring the two coordinates, in the cutting center machine, you can automatically obtain the two The intersection of the reference edge: point C, the coordinate (X, γ) of the point C is the reference point of the machining program of the workpiece (20), and its coordinate value will be automatically recorded in the machine. The following will be operated The process cooperates with the program to explain the deductive relationship in the previous section: When the operator finds the coordinates of the first point and enters the n G1 0 〇π instruction, the program in the G instruction module, Ν 〇 9 0 1 0, will be executed.

Definition) When this formula is executed, the value of variable # 501 is equal to 1 (by formula (10) I transports the weight. # 500 of formula (16) = # 4014, which defines the variable # 50, etc.)

Page 11 518264 V. Description of the invention (9) In the system variable # 4014; Learn from Table 6 ^ 入 置 # it. ‘糸 系 变 variable # 4014 is the previous import, which is the first one, and this is the first import of the single node system; tb & μ㈣, whose value is 56. Equation (17) is the defined workpiece coordinate system: gp, 4 跖 p ^ * 马 疋 义 变 ^ 18 = Variable # 500-54, # 18C,; " ° # 518 times 20, the value paid is For 40. The Ganshan system is corrected, the variable two is f, the constant 20 is the workpiece coordinate, and the variable numbers of the coordinate systems are sequentially different by 20, so == the second morning, the system has confirmed the input The coordinate is _, and the formula = lf. Stop: the difference between the variable number of the workpiece coordinate used and the starting coordinate can be obtained. The formula (; [9) Sun Dingxi μ α I y) is the meaning of the meaning # 504 = VAR # 502 1 — 变 π # '八' VAR # 5021, which is known from Table 7 as the mechanical base of the X axis: It is the χ-axis mechanical coordinate value when the amount of A is measured in the fourth figure. Since this mechanical coordinate is the center point coordinate of the main axis (also the center of the edge seeker), as shown in point D of the fourth figure, this mechanical coordinate has a difference from the first reference edge (22), that is, the small diameter part 06 The radius value, so the value of variable # 5〇21 must be ^ the radius value (that is, the variable # 5〇2 of formula (U)), in order to obtain the true X-axis coordinates of the first base J side (22), This true x-axis coordinate value is defined as the variable # 504. Equation (20) defines the variable # 1 00 = 522 1 + # 519, which is 522 1 plus 40, which is equal to 5261. Equation (21) is # [# 1〇0] = # 504, and the variable on the left side of the equal sign is # 526 1 so that the variable # 526 1 forms the coordinate value of the first reference edge (# 504). Please refer to Table 5. Variable # 526 1 is the workpiece coordinate system: X-axis variable of G56, so the coordinate value of the first reference edge (22) is automatically recorded in the X-axis of the workpiece coordinate system G56. Equation (22) is a counting function. The value of variable # 501 is automatically added to become page 12, 518264. V. Description of the invention (10) After the value of variable # 501 becomes 2, it is the same as the first one, so it is not The operation of the first conditional expression will be executed again, and the value of the condition that is not # 50! Also does not match the condition of the second conditional expression, so that :, this: win the conditional expression, and execute expression (31), making the variable # The value of 501 is 10%. At this time, '[# 5〇1EQ3] condition of the second conditional expression is different. After the author completes the second reference edge (24) after the measurement, and the second instruction, the program immediately executes the operation of the second conditional expression.瞀 Define the value of the variable # 505 = # 5022 + # 502, where the variable # 5〇22 ^ Table 7 shows that when measuring the second reference edge (24), it represents the value of the ¥ axis coordinate of the center of the main axis. As can be seen from the fourth figure, when measuring the center point of the main axis and the E point of the second reference edge (24), the radius of the small diameter portion (16) is the same as that of the second reference edge, so the # 5022 After adding the radius value: # 5〇2, the real coordinates of the second reference edge will be set in the variable # 50 5. Equation (26) defines the variable # 1 0 1 = 5222 + # 519, which is 5222 plus 40, which is equal to 5262. Equation (27) is # [# 101] = # 505, the left side of the equal sign forms a variable # 5262, and the variable # 5262 forms the coordinate value of the first reference side (# 505). Please refer to Table 5. The variable # 5262 is the γ-axis variable for the correction of the G56 workpiece coordinate system, so the coordinate value of the second reference edge (2 4) is automatically recorded in the γ-axis of the workpiece coordinate system G 5 6. The obtained X and Y axis data form the (X, Y) coordinates of the C point. Equation (28) makes # 501 return the value 1 again. After the coordinate values of the X and Y axes are obtained, equation (29) is to make this program diverge to the program number 10, which is equation (32), equation (32) is to make the spindle rise, and the command of equation (33) is to return Go to the main program.

To be measured on the workpiece to be processed; To be beautiful: After confirming the workpiece coordinates on the machine, then immediately The intersection point of the reference edge can be obtained through these programs: 2100 instruction, workpiece base? The intersection point is recorded in the system, and it is automatically passed at the specified coordinate of the reference side edge

Because the operator answered the phone or was taken by him; J pieces; ==, when the second to the second point, the measurement can be re-measured. At 0; lJ, enter the "let " instruction, # 可 于此 卫 器On the machine, the system resets the initial parameters and repeats the two-point coordinates required for measurement. Μ. In the present invention, the operator only needs to go through a simple operation step, that is, after measuring the reference edge, enter "Gl00". Instruction, that is to obtain the positive coordinate value of the intersection of the reference edge; however, if the operator forgets the operation steps of obtaining the reference point of the reference edge program, the system also provides the operator with a description of operation steps (HELp) to assist the operator operating. b 'The operator only needs to enter the "G168A100" command in the MDI mode, and the system will execute the ν〇 · 9013 program in the G module.
