Detailed explanation of 11 types of fixed cycle instructions for hole processing in the machining center of the FANUC system

 

Hemm 11 tipi ta ' sett ċiklu struzzjonijiet għal toqba ipproċessar in il FANUC sistema. Xi wħud minnhom huma introdotti hawn taħt.

1) Tħaffir ċiklu kmand G81

Il- G81 tħaffir ċiklu kmand format is:

G81 G△△ X__ Y__ Z__ R__ F__

X, Y huma il pożizzjoni of the hole, Z is the depth of the hole, F is the feed speed (mm/min), and R is the height of the reference plane. G△��� can be G98 and G99. The two modal commands G98 and G99 and G99 control jekk the tool returns to the initial plane or the reference plane after the hole machining cycle is completed; G98 returns to the initial plane, li is is the default mode; G99 returns to the reference plane. When programming, you can use assolut coordinate G90 and relative coordinate G91 programming. It is recommended to use assolut coordinate programming as much as possible.

Il azzjoni proċess is kif ġej:

(1) The drill bit is quickly positioned to the starting point B (X, Y) of the hole processing cycle;

(2) The drill bit moves rapidly along the Z direction to the reference plane R;

(3) Drilling processing;

(4) The drill bit quickly returns to the reference plane R or to the initial plane B.

Dan kmand huwa ġeneralment użat għal proċess toqob lise fond huwa inqas minn 5 darbiet id-dijametru Programmazzjoni eżempju: Il-parti murija in Figura a teħtieġ G81 biex tkun użata għal proċess kollha toqob. The CNC machining program is as follows:

2) Drilling cycle command G82

Il- G82 tħaffir ċiklu kmand format is:

G82 G△△ X__ Y__ Z__ R__ P__ F__

Fi il kmand, P is the pause time of the drill bit the the bottom of the hole, the unit is ms (millisecond), and the meaning of the other parameters is the same like G81.

Dan command adds a feed pause action at the bottom of the hole, that is, is, when the drill bit reachs the bottom of the hole, the tool does make any feed movement and remains in a rotating state to make the bottom of the hole smoother. G82 generally used for enlarging and countersunk holes.

Il azzjoni proċess is kif ġej:

(1) The drill bit is quickly positioned to the starting point B (X, Y) of the hole processing cycle;

(2) The drill bit moves rapidly along the Z direction to the reference plane R;

(3) Tħaffir ipproċessar;

(4) The drill bit pauses feed at the bottom of the hole;

(5) The drill bit quickly returns to the reference plane R or to the initial plane B.

3) Veloċità għolja fond toqba tħaffir ċiklu kmand G73

Għal il ipproċessar ta ' toqob bi a fond akbar minn 5 darbiet id-dijametru 2c peress li huwa fond toqba ipproċessar , li is mhux li jwassal għal ċippa tneħħija , intervall għalf (għalf fi multipli drabi) huwa huwa Il- fond kull wieħed għalf huwa Q% 2c u il-fond ta ' l-aħħar għalf huwa Inqas minn jew ugwali għal Q , il retrazzjoni ammont is d (issettja internament minn is-sistema is sa il- qiegħ ta ' il toqba. Ara Figura b.

Il G73 veloċità għolja fond toqba tħaffir ċiklu kmand format huwa :

G73 G△△ X__ Y__ Z__ R__ Q__ F__

Fi il kmand, Q means kul feed depth is Q, and the meanings of other parameters are the same same like G81.

Il azzjoni proċess is kif ġej:

(1) The drill bit is quickly positioned to the starting point B (X, Y) of the hole processing cycle;

(2) The drill bit moves rapidly along the Z direction to the reference plane R;

(3) Tħaffir ipproċessar, il feed depth is Q;

(4) Retract the tool, the retraction amount is d

(5) Irrepeti (3) u (4) sa il meħtieġ ipproċessar fond

(6) The drill bit quickly returns to the reference plane R or to the initial plane B.


4) Tapping ċiklu kmand G84

Il- G84 ħajt machining cycle command format is:

G84 G△△ X__ Y__ Z__ R__ F__

Il- ħajt tapping proċess jesiġi a strict proportional relationship between the spindle speed S and the feed speed F. Therefore, the feed speed needs to be calculated based on the spindle speed speed during programming. The feed speed F =} magħd magħr veloċità veloċità × thread pitch. The meaning of the oħrajn parameters is the same like G81. The spindle rotates forward when tapping and feeding using G84, and reverse when exiting. What is different from drilling is that the return process after tapping is not a rapid movement, but a reverse exit at the feed speed. Before the instruction is executed, the maspindle doesn even need to be started. When the instruction is executed, the CNC system will automatically start the spindle forward rotation.

Il azzjoni proċess is kif ġej:

(1) The magħżel idur forward, and the tap is quickly positioned to the starting point B (X, Y) of the thread processing cycle;

(2) The tap moves rapidly along the Z direction to the reference plane R;

(3) Tapping ipproċessar;

(4) The magħżel is reversed, and the tap is reversed and returned to the reference plane R at the feed speed;

(5) Meta tuża il - G98 kmand , il taptap malajr jirritorna għal il - inizjali pjan B.

Programmazzjoni eżempju: Tapping the 4 holes in Figure 5-34 with a tapping depth of 10mm. The CNC machining program is:

N02 T01 M06; Use No. T02 tool (Φ10 tap. The pitch is 2mm)

N04 G90 S150 M03; Start the magħżel biex dawwar 'il quddiem 1000r/min

N06 G00 X0. Y0. Z30. M08;
