There is also a wide selection of spindles, software, and accessories to choose from such as laser scanning modules, 2D and 3D digitizing probes, vacuum tables, 4th axis  rotary  tables,  coolant  systems, and tooling.  Arthur chose the 4-foot by 8-foot model which best fi ts his material sheet  sizes  and  his  total  investment including software was under $20,000.   “In the past, producing complicated parts  used  to  be  a  very  diffi cult  and labor intensive task,” Arthur concluded. “It  was  not  unusual  even  for  an experienced  person  like  myself  to ruin a part and have to start that part over. The purchase of a CNC router has  greatly  improved  the  situation. Now, I can program the item once and then reproduce the program with 100% accuracy on the CNC router whenever a customer places an order. The time required to turn out the typical item has been reduced by nearly 2/3. This means that I can help my customers provide better  service  to  their  customers  by delivering furniture in much less time than was required in the past. I have also been able to reduce my prices by an average of 10%, which makes me more competitive. In spite of that price reduction my profi tability has increased because I can now get more done in less time. Clearly, CNC routers have the  potential  to  help  the  domestic custom  furniture  business  compete much more effectively with imports and large chains.” I took a close look at the machine at one of Techno’s technology centers and proved to myself that it could not only handle every job in our shop but also make it possible for us to take on jobs that we weren’t capable of handling in the past.”   Techno’s  LC  series  CNC  routing system  provides  a  number  of  critical features that allow it to deliver accuracy and long-term reliability of a level that has previously only been available from machines at a much higher  cost.  The LC  Series  machine  is  constructed on  a  heavy  steel  base,  includes  a T-Slot  aluminum  table  surface,  ball screws on all threes axes, closed-loop servomotor  drives,  and  comes  with Techno’s  Windows-based  G-Code interface  that  is  upgradable  free  for the life of the machine. These premium drive components offer smooth play- free motion, a high level of accuracy and repeatability, that requires minimal maintenance.  The  closed-loop  servo control  system  provides  constant position  feedback,  higher  power, and  smooth  continuous  motion  that eliminates  the  possibility  of  losing position in the middle of a part. With these high-end features,  it was easy to recognize that we would get high-speed routing and superb cut quality. The new method of producing furniture to order   Arthur now produces most furniture pieces  by  a  new  and  much  more effi cient  method.  His  customers  can provide their designs in the form of paper drawings. Once he has a drawing in a CAD/CAM software program, he makes any desired modifi cations and scales it  to  any  size.  When  he  is  satisfi ed, he automatically generates a G-Code program used by the router to produce the design. He loads the material on the machine, pushes the start button and  walks  away  while  the  router finishes the part. The time required to produce a typical part has dropped from hours to minutes.   As a typical example, Arthur mentioned a  dresser  designed  in  the  form  of  a lighthouse that he builds for one of his customers  in  response  to  consumer orders. The dresser has many pieces with complicated curved surfaces that are required to create a fairy-tale look. In the past, Arthur produced it by fi rst drawing  each  piece  in  full  scale  on paper,  cutting  out  the  paper,  gluing them  to  plywood,  then  cutting  the plywood  to  shape  with  a  scroll  saw, and  finally  sanding  the  board  so  it could serve as a pattern. Each pattern lasted long enough to make three to fi ve pieces, unless it was nicked by the saw used to cut out the fi nished parts. Using this method, it took Arthur about 27 hours to produce the dressers. Now, he imports the drawing into EnRoute 3, converts it to a CAD  fi le, and exports G-Code. Then he loads the machine with wood, pushes the start button, and watches while it cuts out each piece. He can now produce a dresser in only 10 hours, and about half of that time he can  be  doing  other  things  while  the machine is cutting out the pieces. A complete package including training and support   Arthur added that the Techno sales staff  was  very  helpful  in  helping  him select the right machine for his needs and providing the training he needed to  quickly  become  productive.  The machine has proven to be very reliable, not  requiring  any  service  outside  of routine maintenance in the year that he  owned  it  despite  the  fact  that  he keeps it running nearly nonstop. The machine comes fully assembled and includes Techno’s Windows-based CNC G-Code interface with free lifetime software upgrades.  The  machine  is  available in  fi ve sizes, with work envelopes of 30  by  24  inches,  48  by  48  inches, 48  by  96  inches,  59  by  120  inches, and 78 by 120 inches. Each of these models  provides  a  repeatability  of
