Abstract
Plasticfilms with Embossed Micro-Structured Patterns have been Widely Used Inbacklight Guide Panels. the Mass Production of these Films Demands Forultra-Precision Roller Embossing of Micro-Structured Patterns on Plastic Filmsby Precision Pattern Rollers. due to the Heavy Workload and High Precisionrequirements, Ultra-Precision Rollers with Microstructures are very Difficultto be Machined in the Level of Submicrometer Form Accuracy and Surface Finishin Nanometer Range. this Paper Presents Theoretical and Experimental Studies Ofultra-Precision Machining of Precision Rollers with Microstructures. Themachining Mechanism for Precision Roller is Firstly Explained, and Hence Astudy of Effect of Cutting Strategies on Surface Generation in Ultra-Precisionmachining of Micro-Structured Pattern Rollers is Presented. this Includes Thestudy of Different Cutting Trajectories, Length-to-Diameter Ratio of Therollers, Mounting Method for the Rollers, the Number of Cuts in the Formationof the Micro-Structured Patterns, as well as the Time Budgeting for Adoptingdifferent Cutting Trajectories in Ultra-Precision Machining of Micro-Structuredpattern Rollers. the Results of the Study Provide an Important Means Forenhancing the Surface Quality and Optimizing the Time for Machining Precisionrollers.
