SINUMERIK 840D/840Di/810D Operation/Programming ShopMill (BAS) – 10.04 Edition
You can use this cycle to face mill any workpiece. A rectangular
surface is always machined. The rectangle results from corner points
1 and 2 that are pre-assigned with the values of the blank part
dimensions from the program header.
Workpieces with and without limits can be face-milled.
To machine a work piece with four limits select the pocket cycles.
The cycle makes a distinction between roughing and finishing:
Roughing:
• Several material removal operations on surface
• Tool turns above the workpiece edge
Finishing:
• First material removal operation on surface
• Tool turns at safety distance in the X/Y plane
• Retraction of mill
Depth infeed always takes place outside the workpiece.
For a workpiece with edge breaking, select the rectangular spigot
cycle.
In face milling, the effective tool diameter for a tool of type "Milling
cutter" is stored in machine data.
Please refer to the machine manufacturer's instructions.
For vertical machining the start point is always above or below. For
horizontal machining it is right or left.
Machining is performed from outside to inside, if possible.
The starting point is marked in the help display.
