Planar In/Out - Specifies whether the lead move should have any vertical movement associated to it. If you do not check this box, then the arc lead moves have the same amount of vertical movement as the actual threading.
Type In/Out - Use this parameter to select the method of lead move. The parameter settings are:
Arc1 (Arc Radius) - This brings the tool in tangentially to the start of the thread, as defined by the parameters Radius, Angle and Planar.
Direct (Distance) - This method brings the tool directly in to the start of the thread. You must specify the parameter Distance.
Arc 2 (Arc Distance) - This method brings the tool in tangentially to the start of the thread, as governed by the parameter Distance.
Distance In/Out - Defines the radial distance from the thread geometry at which the lead move starts. The tool then feeds into to the piece until it reaches the full cut depth (defined by the parameter Cut Depth on the Thread tab). When the tool has completed a full thread it moves directly away from the workpiece by the value specified in Lead Out's Distance parameter (Direct and Arc 2 moves).
Radius In/Out - Defines the radius of the lead move arc as a percentage of the arc geometry you select for the cycle. The default value is 50%. (Arc 1 moves only)
Angle In/Out - Defines the included angle that lead moves pass through. The default value is 180°. (Arc 1 moves only)
Radius Compensation Factor - If controller compensation is selected the value of the radius compensation factor controls the length of the straight line approach move where compensation is applied. The length of this move is specified as a proportion of the tool radius.
When a CRC factor is used with Pathtrace compensation the straight line move is calculated by multiplying the tool radius with the CRC factor. The start of the compensation move is then calculated as if controller compensation with a full radius offset were being used. The move length seen on screen and in the NC file will be adjusted for Pathtrace compensation to show the move from comp start to the Pathtrace offset toolpath. When working with this method, the Canned Cycle option on the General tab must be checked.
Lead Feeds
Use these parameters to specify the feed rates you want to use in the thread milling cycle. The system adjusts all feed rates to consider the radius of the tool and the radius of the arc of the thread.
Feed In - Specifies the feed rate of the lead in portion of the cycle.
Feed Out - Specifies the feed rate of the lead out portion of the cycle.
