Context

Steel profile punching

The Problem

Creating part descriptions for steel profiles was a manual, error-prone process. Engineers had to interpret drawings, calculate dimensions, select tools, and configure machines by hand—leading to delays, inconsistencies, and rework.

Constraints & Challenges

  • Detection: Detecting holes and profile features automatically from drawings.
  • Mapping: Mapping detected features to punching tools using configurable rules.
  • Calculation: Accurately calculating profile lengths and reference origins.
  • Flexibility: Supporting varying customer requirements and machine setups.
  • Integration: Integrating seamlessly with existing punching machine software.

Our Approach

FDES developed a production-grade AutoCAD plug-in that embeds manufacturing logic directly into the CAD environment.

Steel Profile Tool Mapping Interface
  • Analyze drawing geometry using AutoCAD APIs.
  • Detect holes, slots, and profile features automatically.
  • Map features to punching tools via configurable tables.
  • Generate validated, machine-compatible part descriptions.
  • Provide controlled user overrides where required.

What Was Automated

Automatic hole and feature detection
Rule-based tool mapping
Profile length calculation and validation
Reference origin selection for measurements
Export of part descriptions for punching machines
Optional CSV export and multilingual UI support

Impact

Automated Setup

Automated 90% of manual tool mapping — from 45 minutes per profile to under 5 minutes.

Reduced Time

Reduced machine setup time by 70%, cutting operator dependency from senior to junior staff.

Improved Accuracy

99.5% accuracy in automated part descriptions — virtually eliminating punching tool selection errors.

High Value

Freed 15+ hours per week of senior engineer time for process optimization instead of manual mapping.

Before vs After

Before Automation

  • 45 minutes per profile tool mapping
  • Manual cross-referencing of tooling databases
  • Experienced operators needed for every setup
  • Errors caught only during production runs

After Automation

  • Under 5 minutes per profile
  • Automated tooling selection from rules
  • Any operator can run the system
  • Validation catches errors before production
