CAM software integrated collision checking

  1. 1. The benefits of integrated collision checking in CAM software GUIDE TO www.sescoi.com/camsoftware
  2. 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. www.sescoi.com/camsoftware
  3. 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 www.sescoi.com/camsoftware
  4. 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. 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. 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. www.sescoi.com/camsoftware
  7. 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. www.sescoi.com/camsoftware
  8. 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. 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. 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. 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. 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. 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 www.sescoi.com/camsoftware
