Tapping

Tapping (thread cutting) operations in WSi use two database tables. Screw threads defines which threads are available; Tapping parameters defines how long they take to produce. These tables are edited in the Database Management window.

Screw threads

Defines available screw thread specifications (ISO M, UNC, etc.) and their drill hole and depth parameters.

ColumnDescription
IDUnique identifier
NameDisplay name (e.g. "M5", "M6×1")
Tapping drill hole diameterCore drill diameter before tapping (mm)
Minimal depthMinimum thread depth (mm)
Symmetric toleranceTolerance for symmetric thread positioning (mm)

Tapping parameters

Defines the unit time per mm of thread depth for each combination of process and thread type. WSi uses this table to calculate the machining time for tapping operations.

ColumnDescription
ProcessReference to the process this time value applies to
Screw threadReference to the Screw threads entry this time value applies to
Unit time rateMachining time per mm of thread depth

When a tapping operation is added, WSi looks up the matching Tapping parameters row and calculates: Unit time rate × thread depth.
