Fundamental Principles of NC Programming

2.4 First programming example for milling application

• Create a machining plan
• Translate the work steps into the programming language
• Combine all the individual steps in a program
2.4 First programming example for milling application
Testing first programming steps on the NC
Please proceed on the NC as described below to verify the following programming example:
• Create a new parts program (name)
• Edit the parts program
• Select the parts program
• Activate single block
• Start the parts program

Note
Alarms can occur during program verification. These alarms have to be reset first.
2-22
– Can you use part contours or similar elements, which already exist in other
subprograms or subroutines?
Where is it advisable or necessary to perform zero offset, rotation, mirroring or scaling
(frame concept)?
Define all the machining processes in steps, e.g.:
– Rapid traverse motions for positioning
– Tool change
– Retract to tool change point
– Activate/deactivate spindle, coolant
– Call tool data
– Infeed
– Path override
– Approach contour
– Retraction from the contour
– etc.
– Enter each individual step in an NC block or blocks.
