Processing programming and matters needing attention

Side drilling processing case: Drilling at Z-10 of 40mm bar material, using 4.2mm drill bit.

 

 

The symbols in Figure 1 indicate the following actions

Positioning (fast movement G00)

Cutting feed (linear interpolation G01)

P1: Pause time programmed by the address P instruction

Ma: C-axis clamping M code output (a value is set in the parameter (N0.5110))

M(a+1): C-axis release M code output

P2: Pause time set by parameter (NO. 5111)

 

Code execution process

The tool is quickly positioned from the starting point to the hole position (that is, the point determined by the hole position data on the initial plane, execute Ma);

Quickly locate to point R;

Cutting feed to the bottom plane of the hole;

Suspend the timeout specified by P;

Quickly return to the plane of point R, execute M(a+1) and pause for the specified time of P2;

Quickly return to the initial plane;

The drilling cycle ends.

Side tapping processing case: tapping at Z-10 of 40mm bar material (holes have been drilled with a 4.2mm drill bit), using M5*0.8 taps.

 

The symbols in Figure 3 indicate the following actions

Positioning (fast movement G00)

Cutting feed (linear interpolation G01)

P1: Pause time programmed by the address P instruction

Ma: C-axis clamping M code output (a value is set in the parameter (N0.5110))

M(a+1): C-axis release M code output

P2: Pause time set by parameter (NO. 5111)

 

The tool is quickly positioned from the starting point to the hole position (that is, the point determined by the hole position data on the initial plane, execute Ma);

Quickly locate to point R;

There are multiple feed and retreat processes: in the initial cutting from point R, the spindle is rotated forward, and only the cutting amount q specified by address Q (action 1) is cut in, then the spindle is reversed and only the parameters are returned After the return amount d (action 2) set in (NO.5213), the spindle is rotated forward to perform (d+q) cutting. (Action 3) After this, before reaching the bottom of the hole (point Z), repeat 2 and 3;

Pause at the bottom of the hole for the pause time specified by P1

The spindle starts to rotate in the reverse direction, the tapping axis retracts to the plane of point R at the speed specified by F, and the spindle stops rotating when it reaches the point R; execute the C axis to release the M code M (a+1), and pause for the pause time specified by P2 ；

Quickly return to the initial plane;

High speed deep hole rigid tapping ends

03Precautions for end face drilling and tapping

Switch to ZpXp plane (G18)

If the tapping is one tap to the end, please modify the parameters 5213 (change to 1000), 5104#6 (change 0 to 1), 5200#7 (change 0 to 1);

Pay attention to the forward and reverse rotation of the second spindle
