Side drilling and tapping with GSK988TD

 

Processing programming and precautions

Case of side drilling: drilling holes at 40mm bar Z-10, 4.2mm drill bit is selected.
 
The symbols in Figure 1 indicate the following actions
Positioning (fast moving FG00).
Cutting feed (linear interpolation G01).
P1: Pause time programmed by address P instruction.
Ma: C axis clamping M code output (a value is set in parameter (NO.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 on the initial plane determined by the hole position data), execute Ma;
Quickly locate to point R;
Cutting feed to the bottom plane of the hole;
Suspend the pause time specified by P;
Quickly return to the R point plane, execute M(a+1) and pause P2 for the specified time;
Quickly return to the initial plane;

Side tapping processing case: tapping at 40mm bar Z-10 (the hole has been drilled with a 4.2mm drill), and the M5x0.8 tap is used.
 
 
 
 
The symbols in Figure 3 indicate the following actions
Positioning (fast moving FG00).
Cutting feed (linear interpolation G01).
P1: Pause time programmed by address P instruction.
Ma: C axis clamping M code output (a value is set in parameter (NO.5110)).
M(a+1): C axis release M code output.
P2: Pause time set by parameter (NO.5111).
 
 
 
 
Code execution process
The tool quickly positions the point from the starting point (that is, the point on the initial plane determined by the hole position data), execute Ma;
Quickly locate to point R;
There are multiple feeding and retreating processes: During the initial cutting from point R, the spindle is rotated forward, only after cutting in the cutting amount q specified by address Q (action 1), 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 to pause the time specified by P1;
The spindle starts to rotate in the reverse direction, the tapping axis retracts the tool to the R point plane, to the R point plane at the speed specified by F, and the spindle stops rotating at the R point; execute the C axis to release the M code M (a+1), and pause Pause time specified by P2;
Quickly return to the initial plane;
The high-speed deep hole rigid tapping ends.

03 Matters needing attention in end face drilling and tapping
Switch to the ZpXp plane (G18);
If the tapping is to the end, please modify the parameters 5213 (change to 1000), 5104#6 (change 0 to 1), 5200#7 (change 0 to 1);
Note the forward and reverse rotation of the second spindle.
