CRT four-axis automatic welding (laser welding or other welding) system advance and retract explanation

Inclined lift

When editing graphics, spot welding and drag welding have parameters that can be set [feed mode] and [retract mode]. The "feed and retract mode" is an actual processing technology that uses oblique feed and retract to meet the needs of welding points in special positions (as shown in Figure 1-1):

This system has designed 7 modes (0 to 6) for the inclined-stayed mode, which are:

0 -> No elevation

1 -> Raise only 1 (1)

2 -> Raise only 2 (2)

3/4/5/6 -> Slant pull mode 3 to Slant pull mode 6

⑴ Feed and retract settings:

In the first interface of the handheld box, select [3. Process Parameters], press the arrow key "→" (non-axis arrow key) to switch to the next page, select [Slant Pull and Lift], and the setting of the inclined pull and lift is shown in Figure 1-2:

As shown in Figures 1-2 and 1-3 above, there are two different parameter setting methods in the inclined-stayed mode setting.

① Raise 1, Raise 2: Only the Z axis is raised, and other axes do not move. 5.0 represents the parameter value of the user-defined parameter Z raising amount.

② Raise 3~6: different directions and distances for advance and retreat. 10.0 represents the parameter value of the user-defined parameter Z elevation, 20.0 represents the length of the inclined bottom edge, and 30 represents the parameter value of the user-defined parameter direction angle, which is used to meet the advance/retract action in different directions.

⑵Use of direction angle:

① Take the positive direction of the X-axis as 0°, and when the X-axis is pointing to the right, the positive upward angle of the Y-axis based on the X-axis increases clockwise, and the positive downward angle of the Y-axis increases counterclockwise.

② The direction angle has positive and negative signs. When the positive angle is clockwise, the negative angle is counterclockwise. When the positive angle is counterclockwise, the negative angle is clockwise.

⑶ Practical application of inclined lifting:

No lifting: After the system finishes executing the previous point and reaches the standby position, it does not perform the lifting action (moving to above the current recording point) and moves directly to the position of the current recording point.

Only raise 1, only raise 2: After the system finishes executing the previous point and reaches the standby position, it moves to the height above the current recording point (determined by the set height value) at the idle speed, and then moves to the set position (processing point) on the Z axis at the feed speed.

Lift 3~6: After the system finishes executing the previous point and reaches the standby position, it moves to the upper side of the oblique pull of the current point (set position) at the idle speed, and then XYZ moves to the set position at the feed speed; the upper side of the oblique pull is determined by the XY offset automatically calculated by the Z-axis lifting setting, the bottom edge of the oblique pull, and the direction angle;

For example:

In Figure 1-4, the Z-axis elevation is set to 4mm, the bottom edge of the inclined pull is set to 5mm, and the direction angle is set to 45°. When the tool is fed in/out, the motion trajectory is shown in the inclined pull trajectory (blue line) in Figure 1-4. The Z-axis elevation is the elevation height of the Z axis set by the user, and the bottom edge of the inclined pull is the straight-line distance of the XY axis set by the user. When the direction angle a is set to 0, the upper side of the inclined pull is located in the (X, -Y) direction of the processing point, as shown in the inclined pull trajectory (blue line) in Figure 1-4. When the direction angle a is set to 180<270, the upper side of the inclined pull is located in the (-X, Y) direction of the processing point, as shown in the green line in Figure 1-4. The same applies to other angles.
