Users can choose to use the CAM functions or continue to use DIFFSYS as they have in the past. The new functionality is an integral part of all DIFFSYS options.
ZEMAX FILE IMPORTS UPDATE
This update covers features contained in DIFFSYS 5.1.2, 5.1.3, and 5.1.4ĭIFFSYS 5.0 is a step change in functionalityĭIFFSYS now has full CAM system capabilities for generating complete part programs for ultra-precision machine tools. User can also load point cloud that defines the custom outer boundary shape. Now user can create custom outer boundary shape for the surface. User Defined Boundary Shape: Is fully released and is part of the DIFFSYS MC3 module. Import of additional Zemax surface type: Importing FZERNSAG, BICONIC, BICONICZ zemax surface type. This file is imported by chosing “Import Zygo file.” from the Options drop-down menu. Zygo(.int) files can be imported as part of measurement corrections file that has the values in form of Zernike terms. This approach will be more useful for point cloud generation of freeform surfaces Then it considers only intersected points as the surface defined point cloud. Now Point cloud can be generated using Contour spacing method where internally it creates Parametric curves in X and Y directions with the given spacing values. Point cloud generation using Contour Spacing method.
ZEMAX FILE IMPORTS CODE
It can now be edited to any sizeĭiffsys can now import a limited number of surface types from Code V ‘SEQ’ files. Similarily, for Mask Offsets and inner diameter: Previously, when Mask Offsets were used, the inner diameter was set automatically, depending on the mask offset values. This has several uses, for example when a surface is tilted. Previously, the overall C-Axis diameter was fixed, depending on the surface shape. It consists of a sum of Chebyshev terms added to a standard asphere equation. The sag equation in DIFFSYS, z = fn(x,y) is similar to the one in the ZEMAX optical design program. With Cylindrical tools there is no such limitationĬHEBYSHEV equation: compatible with ZEMAX optical design program If the front angle is greater than 20 degrees, then the minimum rake becomes less than 70. Note, with CONICAL tools, this angle is limited by the front clearance angle. RAKE angle increased from –45 to –70 degrees Earlier version was always exported with no tool. It is modified to export the file with tool compensated values for diamond tool. For Raster CXZ and Spiral XYZ toolpaths, all associated settings, rake calcs, measurement corrections, graphics etc have been altered accordingly STEADY X tool path is now supported for XYZ spiral Pattern for diamond tool turning. STEADY X new working for XYZ spiral pattern
With this new List Order is added (Sorting N then -M) that corresponds to Zernike Code V file format. Now Zernike surface types can be imported through Code V file format.
