Circular path CT
Application
You use the circular path function CT to program a circular path that connects tangentially to the previously programmed contour element.

Requirement
- Previous contour element programmed
Before you can program a circular path with CT you must program a contour element to which the circular path can connect tangentially. This requires at least two NC blocks.
Description of function
The control moves the tool on a circular path, with a tangential connection, from the current position to the defined end point. The starting point is the end point of the preceding NC block. You can use at most two axes to define the new end point.
When contour elements uniformly merge into another without kinks, then this transition is referred to as tangential.
Input
11 CT X+50 Y+50 LIN_Z-2 RL F250 M3 | ; Circular path with linear Z-axis superimpositioning |
To navigate to this function:
Insert NC function All functions Path contour CT
The NC function includes the following syntax elements:
Syntax element | Meaning |
---|---|
CT | Syntax initiator for a circular path with a tangential connection |
X, Y, Z, A, B, C, U, V, W | End point of the circular path Entry: absolute or incremental Optional syntax element |
LIN_X, LIN_Y, LIN_Z, LIN_A, LIN_B, LIN_C, LIN_U, LIN_V or LIN_W | Axis and value of the linear superimposition Entry: absolute or incremental Linear superimpositioning of a circular path Optional syntax element |
R0, RL, RR | |
F, FMAX, FZ, FU, FAUTO | |
M |
Note
- The contour element and the circular path should contain both coordinates of the plane in which the circular path is executed.
- The Form column allows toggling between the syntaxes for Cartesian and polar coordinate input.
