Generally speaking, these attributes make Lexan polycarbonate an excellent material for applications where you’re not as concerned about aesthetics as you are about creating an extremely resistant protective surface. The RMS can be calculated using the following equation [ 15 ]: where is the average -axis value within the observed area, is the local -axis, value and Renishaw has added a new probe option for its revolutionary REVO® five-axis measurement system, which for the first time, allows surface finish inspection to be fully integrated within CMM measurement routines. Such nonpolar surfaces are show low adhesion strengths to any coating substance. Not every mold finish produces the same results with every material. Severe roughness can cause the gage to display low thickness values (distance #2). The low surface energy of polypropylene makes it extremely difficult to get good bed adhesion even with heated beds. Friction factor test on high density polyethylene pipe. Done. 5-3 • Sand Casting Poor 12-25 Metal forming Kinematic roughness-based surface finish prediction is known to often under-predict the measured surface roughness in turning process, especially at small (micron level) feed rates.
