MILLING

CAM System for High-precision Machining



High-precision CAM system with totally simplified operating environment, utilizing the reliable "CAM calculation program".

For 3D CAM, the reputable CAM-TOOL's CAM strategies for polygon and surface shapes are adopted.
High-precision and high-efficient machining can be provided, as users operate the system to match the required products quality.



User Interface









[ Main Menu ]
The user-friendly interface enables the user to create NC data easily, using the main menu in order from the left. To create NC data, users only need to prepare a machining project and apply a template, then start CAM calculation and check the results.

[ Project Setting ]
All parameters related with machine settings, such as “Project type” (3-axis or Multi-axis), “Shape to machine”, "Stock", "Cutting origin" and "Tool initial position", can be specified on the single dialog box.

[ Process List ]
"Process List", corresponding to the project tree view, assists in the safe and accurate operation. Some parameter values can be confirmed and revised on “Process List” too.

[ Template ]
Template is the function to save and recall standardized processes. Users can apply reliable machining processes easily after machining projects or processes are registered as “Favorites”.

[ Machining Process ]
Main dialog box consists of only main parameters. Others are allocated on detail dialog box. Specifying a formula by using "Macro variables" as a parameter value is also available. This allows the revision of some input values automatically, such as lead-in radius relating with tool diameter, when tool-diameter or feed-rate, etc. are changed.

CAM Function

[ Optimization / Cutting Simulation ]
In addition to the Optimization system like CAM-TOOL's, there is a Simulation process that uses the Tool and Holder data from the Tooling DB to verify safe results. “Delete air-cut”, “Auto clearance” and etc. help users to create more efficient and safer tool-paths too.

[ CL Editor ]
CAM-TOOL's reputable CL editor is adopted into the system, which provides the verification and edit functions of tool-paths, such as "CL Display", "CL Information", "Move/Copy", "Delete", "Change Approach Position", "Change F Value" and etc.

[ Tooling DB ]
"Tooling DB" manages cutting-tools, holders and machining conditions. Users can define the shank with multistage taper or R-shape, and this makes an interference check more precise. Cutting-tools and holders can be prepared easily by downloading catalog data of tool/holder manufactures from WEB site.

3D CAM

For 3D CAM, the reputable CAM-TOOL's CAM strategies for polygon and surface shapes are adopted.

 

    [ Z-level Roughing ]

    Create Z-level offset tool-paths for roughing. "Insert trochoid" and "Insert R" reduce the cutting-load, and contribute to keeping a constant feed-rate. Non-rectangular solid can be specified as "Stock", which allows users to create flexible tool-paths corresponding to machining conditions.


    [ Rest Machining ]

    The system automatically detects the uncut area of previous process, and generates tool-paths for the remains. It is possible to machine efficiently for each portion, cutting by along-surface tool-paths at gently sloping area, and cutting by Z-level tool-paths at steep and groove area. The uncut area can be recognized correctly since any types of cutting-tool (ball/radius/square end-mill) can be utilized.


    [ Z-level Finishing ]

    “Z-level Finishing”, which performs climb milling, assures quality high speed and high-precision machining. Spiral tool-paths can be also created, which contributes to the reduction of connecting-moves. This is the best way to machine automatically since gently sloping area and horizontal area can be also executed at once.


    [ Corner Processing ]

    Creating tool-paths for concave ridge-line portion where smaller cutting tool is often used. It is possible to reduce the cutting-load because the system controls cutting direction automatically corresponding to the angle of the ridge-line. Moreover, "Driving-in", which removes the stock step by step, contributes to maintain a consistent cutting-load.


    [ Low Angle Finishing ]

    The system extracts gently sloping portion automatically by specified angle, and generates tool-paths there. Users can select "Scanning” or "Offset Path" (around the area) as a traveling type, so that it is possible to machine efficiently corresponding to the feature of "Shape to machine".





    [ Surface Finishing ]

    Creating tool-paths along the mesh direction of the specified surface. This cutting mode is useful for additional-machining and part-machining, and also considers the safety of processing for the gap between surfaces.





    [ Curve Cutting ]

    This cutting mode corresponds to the engraving for "Sketch" or "3D Sketch" entities. It is possible to machine groove-portion, edge-line and letters-on-surface precisely, utilizing "Drive Z" function.





    [ Pencil Cutting ]

    Not only ball end-mill but also radius and square end-mill can be used for pencil cutting. Tool-paths are created along the edge-line which the system automatically detects.





    [ Horizontal Area Cutting ]

    The system automatically extracts horizontal area from “Shape to machine”, and generates tool-paths there. Tool-paths are supposed to travel around the area with climbing-cut direction. This cutting mode is useful to machine horizontal area with radius or square end-mill.



 












HOLE / 2DCAM

Hole and 2D machining are integrated to 3D machining project. 2D and Hole entity, Template, Cutting DB drives CAM automation.

[ HOLE ]
It is possible to create drilling data on not only a plate but also 3D surfaces. Corresponding to "Canned Cycle Drilling", "Chamfering", and "Circular Hole Cutting".
[ 2.5D ]
It is possible to create 2.5D machining data, by recognizing "Sketch" entities or "3D model data". Cutting modes of "2.5D Rough Cutting", "2.5D Side Cutting", "2.5D Plane Cutting" and "2.5D Re-machining".

Wire

Wire-cut contours can be recognized easily from model data. The system provides users necessary wire-cut data, with high-flexible cutting pattern and variety of lead-in type.

3+2 Axis / Simultaneous 5-Axis

[ 3+2 Axis ]
High-precision 3+2 axis machining data of HOLE/2.5D/3D millings can be created, defining the machining direction for each process. "Delete air-cut" for multi-axis machining is also available in "Optimization".

[ Simultaneous 5-Axis ]
* Scheduled in future

Cutting Sample

[ Name ] Hub
[ Material ] S50C(13HRC)
[ Size ] 70mm x 70mm x 30mm


Hub cavity has 4 core cone at gradient surface. Since there are remaining area which the roughing tool can’t cut into, remaining volume can be unequal. Furthermore, it has turned edges which the tool load becomes large.

《 Point 》
(1)Rest machining with low tool load variation.
(2)Smooth movement to keep off cutter mark by instantaneous dwell at turned edge.

[ Name ] Brake lamp
[ Material ] NAK80(38HRC)
[ Size ] 100mm x 60mm x 30mm


Brake lamp has machined with Z-level Roughing, Rest Machining, Z-level Finishing, Scanning, and Corner Processing.
[ Z-level + Low Angle Finishing ]
Since the second step is not a horizontal plane but tilted plane, it was machined by Z-level Finishing with constant cusp height. The bottom flat area was machined by Low Angle Finishing. With this combination, it was machined with few approaches and escape even if the gradient changes dramatically.
