CAM software integrated collision checking Presentation Transcript

  • 1. The benefits of integrated collision checking in CAM software GUIDE TO www.sescoi.com/camsoftware
  • 2. The benefits of integrated collision checking in CAM software
    • What is collision checking?
    • A means of detecting interference between the tool holder, the machine tool and the workpiece.
    • However, collision checking integrated into CAM software gives you much more than a stand-alone toolpath verification system.

  • 3. Benefits of collision checking
    • Eliminates the need for machine prove out trials.
    • Parts made right first time
    • No damage to the machine or workpiece
    • Ability to safely run machines unattended - greatly improving productivity
    • Extended tool life through steady tool loading
    • Instils confidence in the quality of the machining process

  • 4. Limitations of stand-alone verification
    • Stand-alone verification relies on cutter location data.
    • Errors found during stand-alone verification require time consuming correction and re-post-processing in the CAM software
    • Integrated CAM and verification finds the errors as programming progresses
    www.sescoi.com/camsoftware
  • 5. Benefits of integration
    • Integrated collision checking gives -.
    • Real time collision avoidance
    • Suggestions for alternative toolpaths
    • The ability to edit the toolpath as programming continues
    • Elimination of an extra external program verification step
    • Simplicity – only one system to learn
    www.sescoi.com/camsoftware
  • 6. Why not stand-alone verification?
    • CAM systems like WorkNC are very reliable, so external verification duplicates effort.
    • Corrections require reprogramming in the CAM software.
    • Extra training will be required to operate the stand alone system
    • Collision avoidance rather than detection is impossible.

  • 7. Collision avoidance – how it works
    • The CAM software knows exactly where excess material is located.
    • Machine travel and rotational limits are considered.
    • The software creates only uncollided toolpaths
    • The software suggests tool lengths to reach other areas of the job
    • Rotate, flip and unwind moves are automatically added as rotational limits are reached.

  • 8. Collision avoidance with 5-axis machining
    • Collision avoidance is particularly valuable for 5-axis machining.
    • Complex machining can be done safely and with confidence
    • Promotes the use of the shortest and most rigid cutters
    • Minimizes axis rotation moves to speed up cycle times
    • Enables more of the component to be completed in one operation
    www.sescoi.com/camsoftware
  • 9. WorkNC Auto 5 and collision avoidance
    • WorkNC Auto 5 automatically changes 3-axis toolpaths into 5-axis
    • Collision avoidance is applied during programming
    • Nine options for controlling the toolpath trajectory
    • Flip and unwind moves added as axis limits are reached
    • Takes account of the kinematics of individual machines
    www.sescoi.com/camsoftware
  • 10. Visualising the machine
    • Both stand-alone and integrated collision check systems can model the complete machine
    • Most useful for individually programmed 5-axis machining operations when collisions are more likely
    • VisuNC in WorkNC shows collisions or near misses. The programmer can edit these toolpaths immediately.
    • WorkNC Auto5 avoids collisions as it calculates
    www.sescoi.com/camsoftware
  • 11. Is it completely machined?
    • Some stand-alone systems can compare the finished part with the original model
    • Rest models in CAM software show where the excess material remains
    • Extra machining operations can be added as programming continues, to remove the excess material
    • Graphics show areas which need spark eroding where further machining is impossible
    www.sescoi.com/camsoftware
  • 12. Optimizing the toolpath
    • Some stand-alone systems can optimize feedrates and rapid movements
    • WorkNC already produces optimized toolpaths
    • WorkNC uses climb milling if possible, smoothes trajectories and eliminates unnecessary retract moves
    • For extra optimization Sescoi offers NCSpeed which works on the postprocessed code to fine tune feedrates
    www.sescoi.com/camsoftware
  • 13. Safety and productivity
    • Modern CAM software is very reliable. WorkNC defaults to safe toolpaths
    • Advanced systems like WorkNC produce high quality fast cutterpaths
    • Auto 5 technology brings 5-axis machining with collision avoidance within the reach of every engineer
    • Except in special circumstances stand-alone verification duplicates effort
