New Hole Feature dialog - Thread tab

www.kxcad.net Home > CAM Index > EdgeCAM Index >

Use this tab to create new threading information or to amend the information imported from a solid CAD system.

Apart from Depth, the threading information cannot be explicitly used as the basis for machining (unlike other feature properties, such as the Level and Depth values in the Geometry tab). You could however use the information in strategy manager to select the appropriate tool.

Tapped	Whether the hole has threading information. When edging, check to start defining threading information.
Standard	If you want to define a standard thread, such as 'ANSI Metric', select this here. This cannot be set on importing from CAD systems (will be left at 'None').
Nominal Size	The nominal size for the specified Standard thread selection (above).This might be a true size dimension (usually a diameter), or a gauge or reference number. Once you have selected a value, other threading values are be automatically set from the threads database. This cannot be set on importing from CAD systems (will be left at 'None').
Thread Units	The units that the size values in this dialog, such as Tap Diameter,are specified.
Tap Diameter	The tap diameter. See 'Thread Units' above.
Drill Size	The tapped drill size. See 'Thread Units' above.
Clearance Drill Size	The clearance drill size. See 'Thread Units' above.
Pitch/TPI	Specifies the pitch of the thread or the number of threads per inch dependingon the thread specification.
Hand	Whether the thread is right or left-handed thread.
Full Depth	Check this for the threading to extend to the bottom of the hole.
Depth (in Part Units)	The depth of the tapped part of the hole.

The hole feature will not be 'fully defined' (as indicated by a '?' in the Features Window) if 'Tapped' is checked and any of these values are not defined: Thread Units, Tap Diameter, Drill Size, Pitch/TPI, and Depth.
