These parameters specify the details of the tool to be used in this cycle. The only information the system uses from the Toolchange command is the tool diameter.
Number of Teeth – Defines the number of teeth on the tool.
Overlap of Teeth – This parameter defines the number of teeth to be overlapped by this cycle. The overlap cannot exceed the number of teeth on the tool.
Tools with the same number of teeth less the Overlap value produce the same toolpath.
For example, a tool with 6 teeth and an overlap of 2 teeth produces the same toolpath as a tool with 4 teeth and no overlap.
Pitch of Tool - Specifies the pitch of the teeth on the tool. It must be equal either the pitch of the thread or the lead of the thread.
The lead of the thread is calculated as follows:
Lead = Pitch of thread x Number of starts
Taper Angle – Specifies the internal angle of the tool, and therefore the angle of the thread to be cut. See under Cutting a Tapered Thread.
Hand of Tool – Selects the hand of tool to be used, and together with Mill Type indicates the direction of milling. See Determining the Thread Mill Cut Direction.
