Air Cuts Only optimization
This session shows how to optimize the NC program’s Air Cuts only (tool motions not
in contact with material) based on the NC machine’s rapid rate.

1. Set VERICUT to optimize the current NC Program’s air cuts
only
•
Ribbon Bar > Optimize tab > Optimize group >
Optimize Control
Note: The Optimize Control command button opens the Optimize Control
window enabling you to control when NC program files are optimized by
OptiPath or Force, specify the file to receive the optimized data, choose the type
of stock material and NC machine involved in the cutting the workpiece. Feed
rates and spindle speeds can be monitored via the Status window. A summary of
the cutting conditions encountered during optimization and min/max optimized
feed rates is written to the Log and available for use when creating a report file
showing an overview of the results of the current VERICUT session.

•
Mode: use pull-down and select Air Cuts Only
Note: This option is useful for reducing time of proven NC programs, without
affecting cutting feed rates and resulting surface finishes. Air Cuts Only mode
optimizes air cuts (tool motions not in contact with material) only and does not
change their trajectory. Using this mode does not require an OptiPath or Force
license.
•
Optimized File: use to specify the name of the modified (optimized) NC program
file to receive optimized NC program data.
•
•
Check Break-up Partial Air Cuts
Air Cut Feedrate leave Default checked
Note: The Default value is obtained from the VERICUT machine’s X
Component > Accel/Decel > Max Feed Velocity value.

2. Monitor the Optimization with the Status window while
cutting.

Play
Note: The VERICT Logger indicated that the optimized file has been created
It’s about an 5% improvement.
Note: The Optimization Savings Calculator window enables you to enter shop
specific information and use the information available from OptiPath or Force to
calculate both the part savings, and the workshop savings associated with using
OptiPath or Force. User entered settings are stored in the Preferences File.
OptiPath or Force data must be available before you can open the Savings
Calculator window.

3. Review the VERICUT log file
•
•
Ribbon Bar > Info tab > Report group >
Scroll down to the Tool Summary section
VERICUT Log
Note: The VERICUT Log window displays the VERICUT Log file. This file contains
session information, such as error, warning and informational messages about the
verification session. In this window, you can view, print, change the name and save, or
reset Log file contents.

4. Compare the original NC Program with the optimized one
•
•
•
Ribbon Bar > Optimize tab > Optimize group >
Compare Files
Browse the Original and Optimized NC Programs as shown below
Select Compare
Note: The Compare Files command button opens the Compare NC Program
Files window enabling you to select and compare the original NC program file
and the optimized NC program file.
5. Test with other rapid rates
•
Repeat steps 1-4 and test with different Air Cut Feedrates to get more
comfortable with the Air Cuts only mode.
Conclusion
This session has shown you how to optimize the NC program’s Air Cuts only (tool
motions not in contact with material) based on the NC machine’s rapid rate.
