(some col.) ;c30 cm.+e1 CD-ROM  aProject paper (Bachelor of Mechanical Engineering with manufacturing) -- Universiti Malaysia Pahang - 20083 aThe present thesis discusses the development of the statistic model surface roughness   for  acrylic  sheet on  laser beam  cutting  and  the  effect  of  laser  beam  cutting  (LBC)   parameters  towards  acrylic  sheet  surface  roughness.  The model  are  developed  by   using  the  response  surface  methodology  (RSM)  to  study  the  effect  of  cutting   parameters  (power,  laser speed,  gap  distance  and  material  thickness)  on  acrylic   sheets surface roughness. The model of the experiment is performed with using Box-  Behnken  design which  it  will  arrange  all  the  cutting  parameters  with  suitable   combination  that  needed  for  experiments  performance.  The  affect  of  input  factors   and  the  interaction between  these  factors are  also  investigated  in  this  study.  It was   found  that  the  interaction of  these parameters (power,  laser speed, gap distance and   material  thickness) with  surface  roughness  was  extremely  strong.  The  predictive   models  in  this  study  are  believed  to  produce  value  of  the  surface  roughness. The   predicted model  for  first  order  and  second  order  for  this model  is  performed with   using  MINITAB  software.  MINITAB  will  able  to  give  solution  for  many  data   analysis and then predicted model will come out after finish all the analysis steps. 0aLaser beam cutting  00104071a20000b20000d2019-09-04l0oTJ1191 .A75 2008 rs Bc.p0000038760r2019-09-04 00:00:00t1w2019-09-04yPSM  00104071a20000b20000d2019-09-04l0oCD 3578 | TJ1191 .A75 2008 rs Bc.p0000038761r2019-09-04 00:00:00t1w2019-09-04yPSM  aVIRTUA40c1480d1486  aVTLSSORT0080*0200*0400*0900*1000*2450*2600*3000*5020*5200*6500*9992
