G211. Inside thread milling cycle
[ K5.5 ] Thread depth
It defines the distance between the crest and the root of the thread. If not programmed, the CNC
issues the corresponding error.
[ B±5.5 ] Thread pitch
Defines the thread pitch.
• With a positive sign, the direction of the thread pitch is from the surface of the part to the bottom.
• With a negative sign, the direction of the thread pitch is from the bottom to the surface of the part.
If not programmed or programmed with a 0 value, the CNC will display the corresponding error
message.
[ C1 ] Type of tapping
Defines the type of tapping to be carried out. This parameter depends on the type of tool being used.
• When programming C= 0, the threading will be done in a single pass.
• When programming C=1, it will make one thread per each pass (single-edge cutter).
• When programming C=n (where n is the number of cutting edges of the cutter), it will make n
threads per each pass.
If not programmed, a value of C=1 is assumed.
[ L5.5 ] Finishing stock
It defines the finishing stock at the bottom of the thread. If not programmed, a value of 0 is assumed.
[ A5.5 ] Maximum penetration step
Defines the maximum penetrating pass of the thread. If not programmed or programmed with a 0
value, it will run a single pass up to the finishing stock.
[ E5.5 ] Approach distance
Approach distance to the thread entry. If not programmed, it will enter the thread from the center
of the hole.
[ Q±5.5 ] Thread entry angle
Angle (in degrees) of the segment formed by the center of the hole and the thread entry point with
respect to the abscissa axis. If not programmed, a value of 0 is assumed.
