Threading
Icon: 
Menu: Turning | Turning | Threading
Links:
Make an internal or external threading, on the finish part. The nature of the tool selected defines the type of threading to be done (ISO metric, ISO metric fine, ISO metric trapezoidal, ANSI or other..).
This cycle is called directly by clicking the faces or the profile, where the user wants to apply a threading.
This command calls up, via an adapted post processor, the fixed cycle of the numerical command machine synchronizing the part rotation and the feed movement of the tool.
With this function, the user is able to make classical threadings (tapered, straight, frontal) and multiple tapering threadings in one function. To do that, the user must identify the starting face, where the threading will start and a face where it will end. Of course, usually the start and finish faces are the same.
After, an arrow indicates the threading direction. To obtain a right or left pitch, the user must pay attention to the rotation movement of the part, and to the used tool.
For a right pitch :
Right tool
Right rotation
Threading from the tail stock towards the chuck
Or
Left tool
Left rotation
Threading from the chuck towards the tail stock
For a left pitch :
Right tool
Right rotation
Threading from the chuck towards the tail stock
Or
Left tool
Left rotation
Threading from the tail stock threading towards the chuck
The threaded length is calculated
as follows :
Real threaded length = theoretical threaded length + number of empty threads *PITCH + (Width of clearance groove / 2)
Select the menu
"Turning | Turning | Threading" or click the icon.
If there are several parts, indicate the part to machine.
Click the starting face (or the starting element) for the machining.
Select the last face (or last element) on which the machining should finish. The user can select
The button STARTING FACE or right click when the beginning and end faces are identical in topological mode.
The button ENTIRE PROFILE or right click in automatic mode to machine all the profile.
The button STARTING CURVE when the beginning and end entities are identical in automatic mode.
Select the tool to use for the operation.
Specify the different parameters in the tab dialogue box which appears.
Enter the comment which appears on the machine block listing meant for the NC operator. This comment will also appear when the user wishes to take a look at or modify an operation, using the Operation/ Operations manager function.
Eventually, enter a codified remark which will be interpreted by the post-processor, in a specific manner predefined by the user and the post-processor redactor.
Validate entries made into the dialogue box by clicking on OK.
