How GibbsCAM UKM Can Reduce the Need for Third-Party Simulation Software

CNC machines are becoming more complex.

Modern machines can have:

• Multiple axes
• Multiple spindles
• Multiple turrets
• Live tooling
• Sub-spindles
• Simultaneous machining operations

With this complexity, checking the CNC program before machining is important. Many manufacturers use separate third-party simulation software for this purpose.

GibbsCAM provides Universal Kinematic Machine (UKM) technology with integrated machine simulation. UKM allows GibbsCAM to program, simulate and post-process complex machine configurations within the same CAM environment.

UKM stands for Universal Kinematic Machine. It is designed to handle complex CNC machine configurations.

UKM supports machines with:

• Multiple axes
• Multiple machining flows
• Multiple turrets
• Multiple spindles
• Complex machine movements

GibbsCAM states that UKM can program, simulate and post-process machines with any number of axes and flows.

This makes UKM especially useful for:

• Multi-task machines
• Mill-turn machines
• Swiss-type machines
• Multi-spindle machines
• Multi-turret machines

A major advantage of UKM is the connection between:

• Machine definition
• Toolpath
• Machine simulation
• Post processing

The machine configuration can include:

• Axes
• Spindles
• Turrets
• Tool holders
• Tool blocks
• Fixtures
• Other machine components

This gives the programmer a machine-based view instead of looking only at the toolpath. GibbsCAM also supports machine-specific configurations for complex machine tools.

GibbsCAM includes Machine Simulation for supported configurations. It uses an animated machine model to show machine movement.

The programmer can check:

• Tool movement
• Part movement
• Machine component movement
• Fixture interaction
• Tool and machine interference

GibbsCAM describes Machine Simulation as a verification tool for identifying program errors before machining.

GibbsCAM provides integrated verification features for checking machining problems.

These include:

• Collision checking
• Gouge checking
• Tool movement verification
• Machine movement verification

For 5-axis machining, GibbsCAM provides collision detection and gouge checking for supported tool shapes. Machine Simulation adds dynamic verification of the workpiece, tools and machine components.

For MTM machining, Integrated Process Rendering can show multiple tools cutting at the same time and help identify gouges and collisions.

Simulation is most useful when the machine model and post processor are correctly configured. GibbsCAM's UKM architecture connects the machine kinematics with post processing.

GibbsCAM's documentation states that the post engine uses the same program iterator used for simulation.

This helps maintain consistency between:

• The machine being simulated
• The programmed movements
• The posted CNC output

The result is a more connected programming and verification workflow.

Complex machines can have several movements happening together.

Examples include:

• Turning and milling in the same cycle
• Multiple turrets working simultaneously
• Main spindle and sub-spindle operations
• Live-tool machining
• Synchronized machining

GibbsCAM MTM provides Sync Manager to manage multiple process flows. It can also check for invalid operations and synchronization problems. This allows the programmer to check the machining sequence before sending the program to the machine.

A traditional workflow may require:

• CAM programming
• Toolpath generation
• Post processing
• Exporting the CNC program
• Opening another simulation application
• Loading the machine model
• Loading tools and fixtures
• Running verification

GibbsCAM can bring many of these steps into one environment.

The programmer can:

• Program the component
• Define the machine
• Simulate machine movement
• Check collisions and gouges
• Verify machining sequences
• Post-process the program

This can reduce the need to move between different software applications. For suitable applications, this can make a separate third-party simulation package unnecessary.

Reduced Software Dependency

Fewer applications are required for the programming workflow. Programmers can perform programming and machine verification in GibbsCAM.

Simplified Workflow

Less data transfer between software packages. Fewer separate machine models to manage. Less switching between applications.

Better Machine Utilization

UKM supports complex machine configurations. Programmers can simulate the actual machine setup before machining.

Reduced Programming Risk

Machine movement can be checked before the program reaches the CNC machine. Collision and gouge checks help identify potential problems earlier.

Lower Overall Cost

If GibbsCAM already provides the required verification capability, a separate simulation license may not be necessary.

This can reduce:

• Software licensing costs
• Training requirements
• Maintenance costs
• Workflow complexity

Third-party simulation software can still be useful when a company requires:

• Independent NC verification
• Additional CNC control-level checking
• Separate verification for critical production programs
• Additional verification requirements from customers or internal quality systems

The decision should depend on the company's actual verification requirements.

GibbsCAM UKM should therefore be viewed as a way to reduce or eliminate the need for additional simulation software where its integrated capabilities meet the required level of verification.

UKM brings several important functions together:

• Machine definition
• CNC programming
• Machine simulation
• Post processing

This is especially useful for complex CNC machines. GibbsCAM's current product information specifically highlights UKM's ability to program, simulate and post-process machines with any number of axes and flows.

Machine Simulation can show the relationship between:

• Tool
• Part
• Fixture
• Machine components

This gives programmers a better way to check the complete machining process before production.

Third-party simulation software can provide useful verification capabilities. However, not every manufacturer needs a separate simulation package.

GibbsCAM UKM already provides an integrated approach to:

• Machine kinematics
• Programming
• Machine simulation
• Collision checking
• Gouge checking
• Post processing
