CNC-Calc is an add-on for CIMCO Edit that enables novice programmers to draw 2D geometrical contours, lay out toolpaths for mill and lathe, and simulate the resulting NC program. CNC-Calc is a great tool for the operators and toolmakers who are untrained in the use of advanced CAD/CAM systems. For them, CNC-Calc can help increase productivity and assist in the day-to-day NC programming. For a small company it can be the first step into the CAD/CAM world.
Designed for usability and productivity
CNC-Calc is designed for ease-of-use that enables the user to draw contours fast and easily. It features common functions for drawing lines and circles in relation to the coordinate system and/or existing geometry. Functionality ranges from the plain “horizontal line” to the complex “circle tangent to three elements”. It includes advanced trimming capabilities and an easy point and click approach for toolpaths layout.
CNC-Calc imports DXF files. From DXF files it is possible to generate toolpaths for lathe and mills, such as ISO, Fanuc and Heidenhain controllers. Other features include generation of user-defined compensation types like computer, controller, wear, and reverse wear.
Since CNC-Calc is an integrated part of CIMCO Edit it is an easy task to view, edit, and simulate generated toolpaths. This enables the user to validate programs and thereby optimize the use of machine resources.
The Turning Operations toolbar allows the user to perform various operations used in the manufacturing of parts. All the operations can be exported directly to CIMCO Edit or to the clipboard, for insertion in a user-defined location.
Roughing will create a roughing operation based on a selected outline contour. In this operation it is possible to create both roughing and semi-finishing cuts, but only with one tool.
Facing will create a facing operation. This operation can contain both roughing and finishing cuts, but only with one tool.
Finishing will create a finish operation based on a selected contour. This operation will make only one toolpath that fits the selected contour.
Grooving creates a grooving operation, based on a selected contour. This will enable machining of the areas that could not be machined with either the Roughing or Finishing operation.
Drilling generates operations for drilling a center hole in the part. The drilling operation will be performed as one continuous motion or as pecking with or without dwelling at the end of each plunge.
Threading creates threading operations for inside and outside threads. The geometry of the thread can be entered by hand or selected from tables. The thread geometry can be normal or conical.
Cutoff generates an operation for cutting off the part from the stock. In the operation it is possible to define the corner geometry as sharp, round or chamfered.
Export contour can export a contour that the operator has selected on the drawing. If a controller has smart canned cycles for example a specific roughing operation, the user can create a macro in the editor to support this, and then export the actual contour for insertion in the canned cycle.param
The feed and speed calculator is used to generate tool changes, or to simply calculate the feed and speed, based on the data for a specific tool.
The Milling Operations toolbar allows the user to perform various operations used in the manufacturing of parts. All the operations can be exported directly to CIMCO Edit or to the clipboard, for insertion in a user-defined location.
Face milling creates a facing operation based on a selected outline contour.
Pocket milling creates pocket operations for one or multiple pockets. These pockets can contain multiple islands, or none. In a single operation, it is possible to make both roughing and finishing cuts, but only with one tool.
Contour milling creates operations for contour milling. A contour operation can machine multiple contours with roughing and finishing cuts, but only with one tool.
Drilling creates drilling operations for hole drilling. From a drawing, the hole positions can be selected with the use of a filter, or by simply indicating the hole position. If multiple holes are drilled, they can be arranged in both rectangular and circular patterns.
Helix drilling can generate operations for helix drilling. Like normal drilling, multiple holes can be selected with the use of filters, or by selecting the individual circles from the drawing.
Thread milling can create threading milling operations. The threads can be inside or outside, and can be created for tools with one or multiple teeth. Again, multiple threads can easily be selected with the use of the filter function.
Simple letter milling can generate operations for milling simple letters on the drawing. These letters will have to be drawn using the simple letter function, but then all letters can be selected with the window functions, and machined in operations based on their start and end depths.
Mill TrueType Letters
TrueType letter milling can create operations to mill the outline and/or the interior of the individual letters. The letters can be selected with the window function, and all letters with the same parameters can be machined in one operation.
Export contour can export a contour that the operator has selected on the drawing. If a controller has smart canned cycles, for example a specific pocket operation, the user can create a macro in the editor to support this, and then export the actual contour for insertion in the canned cycle.
Feed and speed calculator is used to generate tool changes, or to simply calculate the feed and speed, based on the data of a specific tool.
First Step into CAD/CAM
CNC-Calc is a great tool for the operators and toolmakers on the shop floor who are not trained in working with an advanced CAD/CAM system.
For them, CNC-Calc can help increase productivity and assist in the day-to-day NC-programming. For a small company it can be the first step into the CAD/CAM world.
