The GibbsCAM 5-Axis Option supports simultaneous 4- and 5-axis machining with various tool types. In combination with GibbsCAM MTM, it also supports sophisticated multi-task machines with live tooling on articulated heads. It includes various machining styles and machining strategies for roughing and finishing, with full tool-axis control, plus application-specific functions such as projection, swarf, electrode, impeller, turbine and cylinder-head machining. For additional accuracy, the 5-axis Option provides collision detection and gouge checking for various tool shapes, with appropriate avoidance options. Toolpath is verified, on the fly, with the integrated GibbsCAM Cut Part Rendering, while GibbsCAM Machine Simulation can provide further verification with dynamic display of work piece, cutting tools and all machine-tool components in motion.
GibbsCAM MTM was specifically designed to address the CNC programming requirements of multi-task machine tools, providing powerful programming tools that are easy to learn and use with the ultimate in flexibility and configurability. Machining processes are easily defined with GibbsCAM's intuitive graphical user interface that provides seamless access to both turning and milling capabilities. And GibbsCAM's associativity allows operations to be updated easily when modifications are made. Factory-supplied post processors output multi-flow NC code complete with utility operations and sync codes.
5-Axis MultiBlade is an addition to GibbsCAM 5-Axis Milling, optimized for programming machining centers and multi-tasking machines (MTMs) to make turbomachinery parts. It simplifies machining blisks, blings and impellers – parts with blades. Its specialized and condensed interface allows easy selection of geometry without having to prepare the model. Users may choose from two levels of functionality, depending on the type of work or level of specialization they pursue.
5-Axis Porting is an addition to GibbsCAM 5-Axis Milling, optimized to simplify machining ports, manifolds, throttle bodies and any tubular openings that change shape and curvature from end to end. The specialized interface is condensed to use only the settings needed for porting operations, making programming much easier and faster. Machining strategies include roughing, rest roughing, and spiral and plunge-along finishing. To control excessive machine motion, 5-Axis Porting uses 3-axis machining as far into the port as possible, and then automatically transitions to full 5-axis to allow for maximum tool reach. All 5-axis motion is calculated for smooth and gouge-free toolpaths. Tool tilting is automatic, at optimal angles, with no need to split surfaces or create tool axis control splines. The software can automatically detect the spine curve through the port and properly align the toolpath. The upper and lower sections of the port can be determined automatically, using maximum tool reach, at the midpoint, or by a user-specified percent of reach, always ensuring proper toolpath blending between upper and lower sections. Overall, 5-Axis Porting makes programming easier and faster, and generates a cleaner, more efficient toolpath for faster and higher quality machining.
Polar & Cylindrical Milling drives one rotary and two linear axes to achieve 3-axis toolpath. It extends GibbsCAM’s standard 3-axis milling functions for use on machines with a rotary axis to enable wrapped geometry, cylindrical and polar rotary milling, and rotary repeats. On mills, rotation is typically around the A or B axis, while on mill-turns C-axis motion replaces Y-axis motion. This C-axis motion can also be applied to the face of a mill-turn part. Input may be flat or “wrapped” wireframe geometry. Wrapped geometry is flat 2D geometry, displayed and machined as if wrapped around a cylinder. Geometry may be created in flat or wrapped mode and toggled between flat and wrapped representations. With this option, all 2D mill processes – contour, pocket, drill, etc. – may be applied to a cylinder. The tool is kept on the centerline of rotation; as a result, there is no control of wall angles or tool engagement. This option also adds the rotary repeat function to milling processes. Output for long, multiple rotations is on a single line of G-code. Post processed output can support a control’s cylindrical and polar interpolation functions. This option is ideal for parts defined by flat geometry, for rotary part features created by the tool’s shape, (such as simple grooves or pockets not needing wall control), and for machines without a Y axis.
GibbsCAM Radial Milling drives one rotary and three linear axes to achieve 4-axis toolpath. It provides a roughing and a finishing mill process for off-centerline “Y-axis” rotary machining, allowing control of wall angles and tool engagement. Input is 3D wire-frame geometry extracted from solids or created by other means, to drive and orient the tool. Optionally, surfaces may be used to orient the tool and limit toolpath. Tool orientation control includes cutting with the side or bottom of the tool, using a surface or two curves to control tilt, following one curve at a specified lean angle, or using progressive tool lean. Toolpath is usually segmented, but can be optimized for helical motion.
GibbsCAM Solids Import provides entry-level support for machining solid models. Solid models can be read, viewed and manipulated. Geometry can be selected and extracted for machining. Using this option you can import a solid model, view it, extract geometry from selected edges, which can then be machined. This option is ideal for users who have been machining wireframe geometry who want to expand their capabilities to support rudimentary machining of solids.
GibbsCAM 2.5D Solids provides significant surface and solid modeling capabilities. Functionality to directly machine surfaces and solids is also included. With this module, you have the ability to create, import and modify solid models and then generate programs to machine them. Specialized tools are also provided to import, repair and automatically solidify surface data. Using GibbsCAM 2.5D Solids, CNC programs can be created faster and easier, making you more efficient and productive.
An extension to GibbsCAM's integrated Cut Part Rendering visualization/verification capability, Machine Simulation uses animated machine tool models to identify any program errors before they cause costly mistakes on the shop floor.
VoluMill for GibbsCAM is an ultra-high performance toolpath (UHPT) option that uses a continuous, high-speed toolpath resulting in an optimized CNC program. These powerful, high-speed, high material removal rate capabilities can help you create the fastest, most efficient toolpath for a wide variety of milling part types in your shop. The process automatically takes into account the best option for milling pockets, including the speed of a tool plunging into the material and material removal rates. Variation in tool load is smoothed, allowing the machine to use much higher speeds and feeds.
GibbsCAM TMS was developed specifically to simplify and streamline the multi-part setup, programming, toolpath verification and post processing for tombstone machining. Within a single, interactive, graphic interface, the TMS dialog provides all the options and flexibility required for CNC programmers to specify and modify machining strategies, and generate efficient, error-free G-code ready for your machines.
Different parts on one face
Fixturing on Multiple Faces
Cutting Tool Access on Three Sides
Rear Window Machining
GibbsCAM TMS provides:
The ability to create a part and fixture combination and have it automatically duplicated in a layout
Various options to automatically locate and arrange parts on a tombstone face
The flexibility to arrange a different part on each face, or mix parts on each face
The ability to program parts or faces at different Z levels
The choice of duplicating an arrangement across all faces or creating different arrangements on each face
The ability to add or clear operations for exceptions on each face, such as part features or machining operations blocked by adjacent workpieces
The ability to set different safe distances for traversing from part to part and indexing (rotating) from one face to the next
Options for optimizing cycle time – by tool, by tool and part, or by tombstone face
Support of subroutines, canned cycles and B-rotation positions in the G-code output
The ability to generate CNC code in single-part mode to prove set up and machining before running a fully loaded tombstone
Optimization is typically dependent on grouping similar or identical operations together to minimize tool changes and rotations of the tombstone. TMS lets the programmer:
Group operations by tool, to minimize tool changes. Machining of part features with a single tool are performed in order and across all parts, before making a tool change.
Group operations by tool and part to minimize traverses. All operations with a tool are completed on a workpiece before moving to the next workpiece. Or, the programmer can choose to have a tool perform a single operation in a group, before moving to the next group.
Complete all operations on a face before moving to another, minimizing tombstone rotation.
TMS provides tools for choosing among these options, and automatically sorts the toolpath, so that it can be verified and tested. Any problems are easily corrected by returning to the TMS dialog and making the necessary modification.
By enhancing TMS with GibbsCAM Machine Simulation, the programmer can render and dynamically simulate the entire setup – tombstone, parts, fixtures, tools, tool holders and all moving machine tool components – to test for interference, collision and cycle time. Simulation also tracks X-Y-Z positions to prevent tools from exceeding a machine’s travel limits.
When the programmer is satisfied with the result, a click of a button in TMS generates a post processed G-code program for the entire tombstone of parts.
Required: TMS is a GibbsCAM Option that requires the 2.5D Solids or SolidSurfacer Options and a customized post processor to generate the appropriate G-code.
Recommended: While not required, the Machine Simulation Option is highly recommended for proper visualization of TMS output.
