7 Programming with Q Parameters 7.8 Example for exercise TNC 360 Three-dimensional machining (machining a hemisphere with an end mill) Notes on the program: • The tool moves upwards in the ZX plane. • You can enter an oversize in block 12 (Q12) if you want to machine the contour in several steps. • The tool radius is automatically compensated with parameter Q108. The program works with the following values: • Solid angle: Start angle Q1 End angle Q2 Increment Q3 • Sphere radius Q4 • Setup clearance Q5 • Plane angle: Start angle Q6 End angle Q7 Increment Q8 • Center of sphere: X coordinate Q9 Y coordinate Q10 • Milling feed rate Q11 • Oversize Q12 The parameters additionally defined in the program have the following meanings: • Q15: Setup clearance above the sphere • Q21: Solid angle during machining • Q24: Distance from center of sphere to center of tool • Q26: Plane angle during machining • Q108: TNC parameter with tool radius Part program 0 BEGIN PGM 360712 MM 1 FN 0: Q1 = + 90 2 FN 0: Q2 = + 0 3 FN 0: Q3 = + 5 4 FN 0: Q4 = + 45 5 FN 0: Q5 = + 2 6 FN 0: Q6 = + 0 Assign the sphere data to the parameters 7 FN 0: Q7 = + 360 8 FN 0: Q8 = + 5 9 FN 0: Q9 = + 50 10 FN 0: Q10 = + 50 11 FN 0: Q11 = + 500 12 FN 0: Q12 = + 0 13 BLK FORM 0.1 Z X+0 Y+0 Z–50 14 15 BLK FORM 0.2 X+100 Y+100 Z+0 TOOL DEF 1 L+0 R+5 Workpiece blank; define and insert tool 16 TOOL CALL 1 Z S1000 17 L Z+100 R0 FMAX M6 18 CALL LBL 10 ......................................................
