WHAT GUIFW OFFERS
Your filament winding project, connected.
Prepare the inputs, build the winding program, review the trajectory and understand the cost of the part.
Winding layers and patterns
Define helical and hoop layers with winding angle, thickness and ramps. Manage entry cycles, staggered lengths and reinforced ends.
Explore winding programsTrajectory simulation
Review the generated winding path and machine motion before exporting the CNC program.
See the tutorialG-code and machine integration
Adapt the post-processor to your controller, export the CNC file and send programs to the machine via FTP on eligible plans.
See CNC compatibilityProduction cost calculator
Combine raw material consumption, machine time and labour to estimate the cost per part and per batch. Included in every plan.
Understand production costsStructural studies and reports
Study pole deflection, pipe pressure and ring stiffness, and tank hydrostatic behaviour with the available engineering modules.

How guiFW generates filament winding G-code
1. Material
Register fiber, resin and catalyst with a bill of materials. guiFW calculates roving and resin consumption for each layer.
2. Mandrel
Choose a tube, conical or capsule mandrel and enter its diameters and lengths. The sketch updates as you type.
3. Machine & payout eye
Start from a ready template (Kollmorgen, Mach3, LinuxCNC, TexComputer), set axis limits, speeds and band width.
4. Program
Stack helical and hoop layers with angle, thickness and ramps, simulate the path and export the G-code file.
CONNECT THE DESIGN TO THE MACHINE
Built for real filament winding machines
- Configurable post-processor: headers, subprograms, motion lines and footers in your controller's syntax.
- Output as .nc, .tap, .txt or .pgm, in metric or imperial units.
- G-code smoothing and line reduction for smoother carriage motion.
- Axis table with limits for mandrel rotation, carriage travel, mandrel approach and payout inclination.
- Send programs straight to the CNC via FTP (Starter plan and above).
More control over each layer
Layer length staggering
Distribute the ends of successive layers along the part.
Reinforced ends
Define two thicknesses with a transition between the end and the body.
Entry cycle management
Control how each layer starts until the winding pattern is established.
Constant free fiber length
Manage the fiber length between the payout eye and the mandrel.
Special functions are available from the Starter plan. Check the limits and features of each plan.
KNOW THE COST BEFORE PRODUCTION
Production cost calculator
Free in every planFrom the winding program to the cost per part.
Choose a product and guiFW loads the raw material its CNC program consumes and the machine time calculated from its G-code. Add labour and your rates to get the cost per part and per batch, or type the data in for any part.

ANSWERS BEFORE YOU START
Frequently asked questions
Explore the tutorial or talk to us about your machine and your production process.
See the tutorialWhat is filament winding software?
Filament winding software calculates fiber paths and CNC machine movements from the mandrel geometry, materials and winding layers. guiFW brings this workflow to the browser, with trajectory simulation and G-code export.
Which machines does guiFW work with?
Any CNC filament winding machine that reads G-code. Templates are included for Fagor, Sinumerik, Kollmorgen, Mach3, LinuxCNC and TexComputer controllers, and the post-processor can be adapted to others.
Is there a free plan?
Yes. The Free plan includes one machine, one mandrel, one payout eye and G-code for cylinders. See all plans on the pricing page.
How much does the production cost calculator cost?
Nothing. It is free in every plan, including the Free plan.
Are structural studies included in every plan?
Structural engineering modules are additional tools with their own scope and availability. Contact us to discuss your project.
