    Can now be calculated from the slope along a meridian angle, or from fixed Outer and Inner angles. This helps eliminate oscillations that can result from calculating the B-axis slope from the surface slope.

    Prerequisite: DIFFSYS A3

    DIFFSYS b slope screen
    Spiral with Linearly Variable Angle

    A new type of spiral that has been added.

    Prerequisite: DIFFSYS A3

    • 2D machining time: Calculation of 2D machining time, dependent on feedrate.
    • Surface finish information: Calculation of diamond tool groove depth.
    • Nearest point with mouse: Moving the mouse in the Toolpath graphics will now show the nearest point for Arc-increment spirals and concentric circles.
    • Toolpath contours are now available for arc-increment spirals and concentric circles.
    • Contours now available for Hemisphere surfaces.
    • Languages page: The QuickSwitch option can switch between two languages, rather than cycle through all languages.
    • DCOF files: The number of decimal places for asphere terms has been increased.

  • Version 5.0.0 +


    DIFFSYS 5.0 is a step change in functionality

    DIFFSYS now has full CAM system capabilities for generating complete part programs for ultra-precision machine tools. The new functionality is an integral part of all DIFFSYS options. Users can choose to use the CAM functions or continue to use DIFFSYS as they have in the past.

    In addition, v.5.0 is going multi-lingual. We’ve added support on the training and main programming screens for German, French, Spanish, Italian, Simplified and Traditional Chinese, Japanese, and Korean.


    CAM 2D, Part Programming Aid (XZ turning)

    Gives users the capability to create complete job files including header, footer, and multi-pass options with a simple to use graphical user interface. CAM 2D is a perfect training tool for new adopters and also a valuable time saving tool for advanced users.

    Prerequisite: any DIFFSYS version.

    DIFFSYS CAM2D screen 1 DIFFSYS CAM2D screen 2

    Multi-language support of the main CAM 2D Basic screen English (top) and Simplified Chinese (bottom) shown


    CAM 3D (XZC turning)

    An integral function of DIFFSYS. The optional packages of DIFFSYS incude multi-pass, multi-tool support for creating full programs for all the part types listed below.

    Prerequisite: DIFFSYS A3, MC, DS, and/or LU depending on part type.

    DIFFSYS 3D polynomial example
    Multi-Tool Library

    Create 2D and 3D part programs using up to three tools. Acommodates different configurations for roughing, semi-finishing, and finishing tools.

    Prerequisite: DIFFSYS A for 2D; DIFFSYS A3, MC, DS, and/or LU depending on part type for 3D.

    DIFFSYS Tool Library
    DIFFSYS 5.0.0 also includes the following new features:
    • Improved accuracy with all equation coefficients up to 14 decimal places
    • Enhanced manuals
    • Enhanced help files
    • Numerous bug fixes

  • Version 4.7.6 +


    DiamondCAM Basic (part programming aid)

    Gives users for the first time the capability to create complete job files including header, footer and multi-pass options with a simple to use graphical user interface.

    Prerequisite: all DIFFSYS versions, including 2D Basic

    DIFFSYS Part Programming Aid
    Diamond Rake Calculation Feature

    It has been significantly improved, accurately calculating the tool/work piece contact point while using negative rake and split radius diamond tools. This significantly improves the part quality of steep surface parts and diffactives.

    Prerequisite: all DIFFSYS versions, including 2D Basic

    DIFFSYS Tool Rake Calculations
    RH (Rhino) Option

    This option will automatically generate 3D point clouds directly from CAD files (IGES, STEP, etc.) and import them into DIFFSYS. Includes a copy of Rhino 5 for Miscrosoft Windows®.

    Prerequisite: DIFFSYS A3 + MC3

    DIFFSYS Rhino import screen
    D-Shape (D-Pocket) Option for Mobile Phone Lens Molds

    This option enables the corners where the D-region starts and ends to now be rounded to give a smoother tool path.

    Prerequisite: DIFFSYS A3

    DIFFSYS D-Shape
    2D Measurement Corrections Now Unlimited

    DIFFSYS had until now been limited to 4 measurement corrections. It is now unlimited, whereby old measurements are added to an archive file.

    Prerequisite: DIFFSYS A + MC2


    New Capability to Directly Import the Most Critical ZEMAX Files

    Including STANDARD, BINARY_2, EVENASPH, XPOLYNOM, XFRESNEL.

    Prerequisite: DIFFSYS A


    Additional Tool Crash Prevention

    If the diamond front clearance is close to hitting the surface, this will appear pink in the contours. This option is off by default (because it's slower) - switch it on in the Toolpath -> Graphics -> Contours Page.

    Prerequisite: DIFFSYS A3


    DIFFSYS 4.7.6 also includes the following new features:
    • Contours display: New features added to the contour display
