Router Applications

Burny / AMC controls operate in the routing industry and our controls can be found on many numerical controlled machines that are routing plastic, wood, aluminum and other materials. A retrofit with a Burny / AMC PC based control can increase productivity by producing more accurate cut parts. Our drive systems produce parts with smoother edges and higher cut quality.

General Motivation make custom signs and awards using special purpose high performance sign making machines they have designed and developed.

Early router machines were controlled by Delta Tau PMAC controllers. These controllers proved extremely difficult to setup and use, much time was spent in producing compatible 2 and 3D job data. Added to this the final overall system performance was poor.

General Motivation chose to use NEE AMC-B's because of:

• The modest system cost
  
  
• The control was easily integrated with their existing job generation software
  
  
• The control was easily integrated with existing brushless drives and motors
  
  
• They expected and achieved great machine performance increases without sacrificing finished part quality
  
  

Burny / AMC undertook all the tasks associated with retrofitting the router controllers. The old control system was removed and the AMC-B fitted, system wiring was modified, the new system was configured and tested and test parts were produced. During testing some limitations were identified with the current machine and improvements suggested. These were implemented by General Motivation improving the machine performance and part quality.

General Motivation were impressed by:

• How easy the router retrofit was, it was accomplished, using the existing Pacific Scientific motor drives in 2 days, this included training
  
  
• The very fast job download time, the machine can be running almost immediately the download is begun, jobs can be downloaded at any time even when the machine is running a part program
  
  
• The high performance of the AMC-B controlled machine - on complex 3D jobs their machines are more than 5 times as productive as it was with the PMAC control. The AMC-B accepts any HPGL (or GM code or ESSI) job file and operates the machine at optimal speed due to the 'time' based look ahead, and to unique vector intersection speed calculations.
  
  
• The quality of parts produced
  
  
• How easy the system is to use, functions can be rapidly accessed by simply labeled keys, pressure sensitive machine jog keys and a pulse wheel make the machine fast and easy to precisely position to 0.0001 inches.
