The Solids Import option provides entry-level support to machine solid models. Solid models can be read, viewed, and manipulated. You can select and extract geometry for machining. With Solids Import, you can import a solid model, view it, and extract geometry from selected edges, which you can then machine. This option is ideal if you machine wireframe geometry and want to expand your capabilities to support rudimentary solids machining.
Solid models are more and more common in manufacturing as a source data type. Solid models provide more accurate geometry than other formats, which reduces errors. GibbsCAM solids-based options are built on the Solids Import option. If you are ready to step up to solids, Solids Import provides basic support to machine solid models in an easy-to-use environment so that you can ease into solids.
Native Parasolid Support
Solid models are available in a wide variety of formats, from industry standards like STEP, to CAD-system-specific formats, to kernel modeler formats. GibbsCAM Solids Import supports Parasolid files, a kernel modeler format widely used by numerous popular CAD systems like Siemens Solid Edge® and SOLIDWORKS®. Sharing a common modeling kernel ensures that you can read CAD models in Parasolid format directly into GibbsCAM and then view and manipulate them. Build your solids-based technology on a solid foundation.
Solid models provide a more complete representation than wireframe or surface models, which allows them to render more accurately. You can choose from a variety of solids display modes. You can orient your view dynamically while also providing quick access to standard views with the innovative GibbsCAM virtual trackball. Get a solid view of what you are machining.
Extracting Geometry from Solids
Solid models contain both wireframe and surface geometry for the richest amount of geometric data. And solid models ensure accurate edge geometry between surfaces. With GibbsCAM Solids Import, you can extract a solid model’s wireframe geometry, which corresponds to the edges of a part, and directly machine from it. Or, if necessary, you can modify the extracted geometry before you machine it. Take advantage of solid model accuracy.
Sometimes, where you want to machine is not necessarily defined by an existing edge. With GibbsCAM Solids Import, you can generate wireframe geometry by cutting the solid with a plane. You can then machine or further manipulate the resulting geometry. Get solid capability built on solids technology.
Foundation for Solids-Based Options
Solids introduce a whole new range of capabilities from data exchange, to visualization, to machining, to verification. With GibbsCAM Solids Import, you can choose to add additional capabilities seamlessly, which further expands your solids-based technology. Read in CAD data in other solid formats like ACIS files, CATIA V4 or V5, Pro/ENGINEER, and STEP AP203 or AP214. Grow at your own pace while you protect your investment.
GibbsCAM 2.5D Solids includes significant surface and solid modeling capabilities and the functionality to machine surfaces and solids directly. Create, import, and modify solid models and then generate programs to machine them. Use specialized tools to import, repair, and automatically solidify surface data. Increase your efficiency and productivity by creating CNC programs faster and more easily.
Whether you import solid models from a CAD system, create your own from scratch, or modify an imported solid to create a manufacturable version, GibbsCAM 2.5D Solids provides a full range of solid modeling functionality with advanced functionality like history trees to support you. And its industry-leading ease-of-use makes working with solids straightforward and easy-to-understand. With its powerful solid modeling tools, you can take full advantage of solid modeling technology.
Importing and Repairing Surface Models
Even with the transition to solids, CAD systems still generate surface models that must be imported and machined. With GibbsCAM 2.5D Solids, you can read in surface models and then repair any problems that you encounter with a broad range of surface modeling tools. And you can create your own surfaces for machining. If you still work with surface models, GibbsCAM 2.5D Solids can still cut your jobs and provide a great migration path to solids-based machining.
With GibbsCAM 2.5D Solids, you do not have to start with solid models to take advantage of solids-based machining. Automatically stitch surface models, whether imported or created, together to create solid models that can then be further modified with the GibbsCAM solid modeling tools or machined directly. Access the tools you need to transition from surface-based to solids-based CAM.
Directly Machining 2.5D Solids
Not only do solid models provide considerable advantages during design, but they also offer many advantages during machining. GibbsCAM developed machining functionalities so that users can machine solids directly and take advantage of the additional information available in solids, which results in improved performance, reliability, and efficiency.
Solids Positioning Tools
Since solid models are the main building block within GibbsCAM 2.5D Solids, it supplies powerful positioning tools so you can position and orient solids quickly, easily, and precisely. Not only are these tools extremely useful when modeling a single part made up of multiple pieces, but they can streamline setting up part models in fixturing significantly. Focus on how things need to be placed, not how to calculate the rotations and transformations to get them there.
Identifying the manufacturable features in a part is a common starting point for a program. GibbsCAM 2.5D Solids includes the Profiler, an innovative interface that interactively defines features like bosses, slots, and pockets. Unlike automatic feature recognition, the Profiler gives you complete control over the geometric elements that are included in a feature. The Profiler can also derive geometry interactively for machining. Its robust, feature-based machining provides you with powerful programming tools.
Automatic Feature Recognition (Holes)
Hole-making occupies close to 80 percent of machining time with most production machining jobs. Holes also represent a significant amount of programming time in production parts. Fortunately, holes are also fairly well-behaved features in solid models. GibbsCAM 2.5D Solids provides an automatic feature recognition (AFR) capability that identifies holes along with their position and orientation and also determines various hole aspects (chamfer, counter-sink/bore, bottom condition) based on the hole's geometry. Leverage the AFR capability to improve your hole-making efficiency and quality.
Streamline hole-making productivity and improve overall quality. With hole-making occupying close to 80 percent of production parts’ machining time, how you identify, group, and program holes are extremely important. The Hole Manager is a front-end to processing hole features that displays the parameters of holes and enables you to group them for processing. The Hole AFR is integrated with the Hole Manager so that you can identify hole features to be directly loaded into it automatically. The Hole Wizard is similarly integrated so that hole information is passed directly for automatic tooling and toolpath generation.
The GibbsCAM Rotary Milling option drives one rotary and three linear axes to achieve a 4-axis toolpath. It provides a roughing and a finishing mill process for off-centerline Y-axis rotary machining for 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, you can use surfaces 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. Typically, it segments the toolpath, but it can optimize the toolpath helical motion.
The Polar and Cylindrical Milling option drives one rotary and two linear axes to achieve a 3-axis toolpath. It extends the 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-turn machines the C-axis motion replaces Y-axis motion. You can apply this C-axis motion to the face of a mill-turn part. The input may be flat or wrapped wireframe geometry.
Wrapped geometry is flat 2D geometry displayed and machined as if wrapped around a cylinder. You can create geometry in flat or wrapped mode and toggle between flat and wrapped representations. With this option, you can apply all 2D mill processes including contour, pocket, and drill to a cylinder. Because the tool is kept on the centerline of rotation, you cannot control 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 like simple grooves or pockets that do not need wall control), and for machines without a Y axis.
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 provides further verification with a dynamic display of work piece, cutting tools, and all machine-tool components in motion.
An addition to GibbsCAM 5-Axis Milling, 5-Axis Porting is optimized to simplify machining ports, manifolds, throttle bodies, and any tubular openings that change shape and curvature from end to end. Its specialized interface uses only the settings needed for porting operations, which makes programming 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.
It calculates all 5-axis motion 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.
It can automatically detect the spine curve through the port and properly align the toolpath. Determin the upper and lower sections of the port 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.
An addition to GibbsCAM 5-Axis Milling, GibbsCAM 5-Axis MultiBlade is optimized for programming machining centers and multi-tasking machines (MTMs) to make turbomachinery parts. It simplifies machining parts with blades including blisks, belongs, and impellers. Easily select geometry without having to prepare the model with its specialized, condensed interface. Choose from two functionality levels for your type of work or level of specialization.
Level 1 includes parts with single splitters and toolpath strategies that include roughing between blades with single splitter support, hub finishing, blade and splitter finishing, and automatic gouge checking on all toolpaths. It includes options for leading- and trailing-edge extension and edge-roll trimming, tilt controls, various intelligent controls for rotating toolpath segments around the part, automatic axis detection, and automatic and user-definable links and clearances.
Level 2 adds support for multiple splitters and sub-splitters; blade fillet machining; tool-axis smoothing; splitter smoothing; additional control for tilt, leading, and trailing edges; toolpath segment sorting; and the ability to define stock for rest milling. Whether toolpath is generated for multi-task machines or machining centers, both levels of 5-Axis MultiBlade use the same post processors as GibbsCAM 5-Axis and the same simulation models in GibbsCAM Machine Simulation.
An extension to the GibbsCAM 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.

The Tombstone Management System (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.
The ability to create a part and fixture combination and have it automatically duplicated in a layout.
Various options to locate and arrange parts on a tombstone face automatically.
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 like 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 setup 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. Perform machining of part features with a single tool in order and across all parts before making a tool change.
Group operations by tool and part to minimize traverses. Complete all operations with a tool 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 to minimize tombstone rotation.
TMS provides tools for choosing among these options and automatically sorts the toolpath so that it can be verified and tested. Easily correct any problems 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 including 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 single click in TMS generates a post-processed G-code program for the entire tombstone of parts.
