Drilling and Defastening

Articulated Arm Drilling

Sometimes the dexterity of an articulated arm robot is the appropriate solution. PaR Systems takes its proven drilling capabilities and 3D vision processing and deploys them on standard robots.

• Integrated 3D vision for target and part feature location
• Proven drill head with servo feed axis, high speed spindle and pneumatic clamping nosepiece provide complete drilling process control to accommodate dissimilar material stack ups
• Integrated precision linear-axis allows the robot to move longitudinally for unlimited work envelope parallel to part fixtures
• Integrated secondary axis encoders when higher precision is required

Wing Skin Drilling

• Large 5-axis systems for large structure drilling operations
• Interfaced with movable part fixtures for part flow efficiency
• Vision technology embedded in the end effector to provide fiducial recognition and part location referencing
• Automated tool changer and storage
• Multiple machines supporting multiple work stations to maximize production

Deployable Drilling

PaR Systems' Deployable Automated Drilling System (DADS) was designed for applications that require access inside a cylindrical structure such as: 

• Engine nacelles
• Fan casings
• Cowlings
• Short sections of smaller fuselages
• Other similarly shaped structures. 

PaR's solution blends extensive specialty crane experience with aerospace precision drilling experience by including a transport bridge that hoists and deploys to multiple work stations. When drilling is complete, the entire system is recovered and transported to a different work station.

Benefits:

• Enables precision location of high quality holes
• Precision machine deployable at multiple work stations
• Small footprint
• Increased accuracy due to rigid structure securely clamped to part fixturing to form a single integrated structure

Defastening

PaR Systems has developed and delivered defastening systems that automatically locate and remove fasteners for wing assembly and maintenance. 

Benefits:

• Elimination of skin damage from disengagement during fastener removal
• Elimination of operator fatigue and repetitive use injuries
• Creates archival map of skin locations and condition
• Drilling of replacement skin to precisely match existing structure
