Milling Contour Spigot (Cycle63) - Siemens SINUMERIK 840D sl Operating Manual

Milling contour spigot (CYCLE63)

Function
You can use the "Mill spigot" function to mill any spigots on the face or peripheral surface.
Before you mill the spigot, you must first enter a blank contour and then one or more spigot
contours. The blank contour defines the area, outside of which there is no material, i.e. there,
the tool moves with rapid traverse. Material is then removed between the blank contour and
spigot contour.
Clamping the spindle
For ShopTurn, the "Clamp spindle" function can be set up by the machine manufacturer.

Machining type
You can select the machining type (roughing, base finishing, edge finishing, chamfer) for
milling. If you want to rough and then finish, you have to call the machining cycle twice (block
1 = roughing, block 2 = finishing). The programmed parameters are retained when the cycle
is called for the second time.
Approach/retraction
1. The tool approaches the starting point at rapid traverse at the height of the retraction
2. The tool first infeeds to the machining depth and then approaches the spigot contour from
3. The spigot is machined in parallel with the contours from the outside in. The direction is
4. When the first plane of the spigot has been machined, the tool retracts from the contour
5. The spigot is again approached in a quadrant and machine in parallel with the contours
6. Steps 4 and 5 are repeated until the programmed spigot depth is reached.
7. The tool retracts to the safety clearance at rapid traverse.
