Hole machining cycles <CYCLE>
<CYCLE> command is used to pass standard drilling cycles G81-G89. Use <CYCLE> command to determine cycle type and process the cycle accordingly. Cycle type is specified by the first parameter, other parameters types and their number depends on the cycle type.
Command:
CYCLE ON(71) | OFF(72) | DRILL(163) | FACE(81) | DEEP(153) |
BRKCHP(288) | TAP(168) | BORE5(209) | BORE6(210) | BORE7(211) |
BORE8(212) | BORE9(213)

Cycle type: 71(ON) – turn cycle on, 72(OFF) – turn cycle off, 163(DRILL) - G81 drilling cycle, 81(FACE) - G82 drilling cycle, 153(DEEP) - Deep drilling cycle, 288(BRKCHP) - Drilling with chip breaking, 209(BORE5) - G85 drilling cycle , 210(BORE6) - G86 drilling cycle, 211(BORE7) - G87 drilling cycle, |
Usually CAM system generates drilling technology similiar to the following:
...
GOTO.abs X, Y, Z ! Position the tool at the first hole.
CYCLE DRILL(163) ! Perform the drilling calling cycle of appropriate type.
GOTO.abs X, Y, Z ! Move the tool to the next hole.
CYCLE DRILL(163) ! Perform the drilling calling cycle of appropriate type.
...
GOTO.abs X, Y, Z ! Move the tool to the last hole.
CYCLE DRILL(163) ! Perform drilling by calling cycle of appropriate type.
CYCLE OFF(72) ! Turn cycle off.
...
The first drilling cycle command should form the NC-block containing a cycle definition (like G81) and cycle parameters.For example:
G81 X_Y_Z_R_F_
Following commands processing should form block containining only the changed registers. For example:
X_Y_Z_
X_Y_Z_
...
X_Y_Z_
The <CYCLE OFF(72)> command should form the code of cancelling cycle. For example:
G80
When developing ISO postprocessors using masks ISO.G operator can be used. The value of ISO.G is set automatically according to the following table:
|
CLD parameter value |
ISO.G value |
|
CLD[1] = 163 |
ISO.G = 81 |
|
CLD[1] = 81 |
ISO.G = 82 |
|
CLD[1] = 168 |
ISO.G = 84 |
|
CLD[1] = 209 |
ISO.G = 85 |
|
CLD[1] = 210 |
ISO.G = 86 |
|
CLD[1] = 211 |
ISO.G = 87 |
|
CLD[1] = 212 |
ISO.G = 88 |
|
CLD[1] = 213 |
ISO.G = 89 |
|
CLD[1] = 153 |
ISO.G = 83 |
|
CLD[1] = 288 |
ISO.G = 73 |
|
CLD[1] = 72 |
ISO.G = 80 |
