Type Q: Tapped Flat Surface Hole
The Start Point is at the center of the Cutter Insertion Hole in the XY plane. Along the Z-axis, it is at the position of the lower edge.
XEBEC Path for absolute positioning (ABS) is generated with the Start Point position as the machine zero point (X0Y0Z0).

Content of XEBEC Path for Tapped Holes (Pre & Fin)
Pre Path: to be used on the clearance hole prior to tapping
-
- Pre Path forms a large edge break at the exit of the clearance hole, to suppress formation of burrs during tapping
- It performs edge breaking in three passes rather than in a single pass to reduce cutting resistance.
Fin (Finish) Path: to be used after tapping to finish
-
- Fin Path forms edge break length of 0.02mm after tapping.
- It removes burrs that are generated during the tapping operation.
Do not use Fin Path if you are using a roll tap |
Steps to Use XEBEC Path for Tapped Holes
- Drill the clearance hole
- Use Pre Path to break edge
- Tapping
- Use Fin Path to finish
Alternative Steps to Shorten the Cycle Time
Drill the clearance hole
Use Fin Path to break edge
Tapping
When omitting Pre Path and using Fin Path only, the Cutter will need to remove a greater amount of material as it travels in the radial direction initially from the Start Point, prior to breaking the edge. For safety, reduce the initial feed rate in the radial direction. After that, continue at the recommended feed rate. |
