Cimatron E11 New! -

Cimatron E11 is a bit older (released around 2013), but it is still widely used, especially for mold & die and 3-axis milling. A "useful post" for E11 depends heavily on your machine + controller (Fanuc, Heidenhain, Siemens, Mazak, etc.) and machine type (mill, mill-turn, wire EDM).

Here’s a breakdown of how to get a useful post for Cimatron E11, what works well, and common pitfalls. cimatron e11

Cimatron E11: A Deep Dive into the Legacy Powerhouse of Mold and Die Manufacturing

In the fast-paced world of Computer-Aided Manufacturing (CAM) and Computer-Aided Design (CAD), software versions come and go. However, few releases have left as lasting an impact on the mold, tool, and die industry as Cimatron E11. Released as a milestone version by 3D Systems (formerly Cimatron Technologies), E11 represents a pivotal moment where 3D design and 2.5-to-5-axis machining became truly seamless. Cimatron E11 is a bit older (released around

Even years after its release, Cimatron E11 remains a benchmark for reliability, speed, and specialized functionality. For many toolmakers, it is the "gold standard" that subsequent versions are measured against. This article explores the intricate features, technical specifications, and enduring legacy of Cimatron E11. Part 5: The Love-Hate Relationship with E11 4

4. Example: Simple Fanuc Post Snippet (GPP2 format)

Inside your .gpp2 file (excerpt):

TOOL CHANGE:
  IF (ToolNum != LastToolNum)
    OUTPUT "M5" ;
    OUTPUT "M9" ;
    OUTPUT "G91 G28 Z0" ;
    OUTPUT "M6 T" ToolNum ;
    OUTPUT "G90 G54" ;
    OUTPUT "S" Speed "M3" ;
    OUTPUT "G43 H" ToolNum ;
  END_IF ;

4. 3D High Speed Machining (HSM)

E11’s 3D HSM strategies were a massive leap forward. Key cycles include:

• Chip Thinning: Automatic feed rate adjustment for circular interpolation.
• Volumetric Milling: Roughing routines that maintain constant tool engagement angle, reducing shock on the spindle.
• Hard Milling: Specific toolpaths for hardened steel (HRC 50+) featuring "stock awareness" to avoid air cutting.
• 5-Axis Link: Multi-axis positioning (3+2) and simultaneous 5-axis swarf cutting for impellers and deep ribs.

Who benefits most

• Mold and die shops working with complex split surfaces.
• Job shops running small batches that need rapid NC turnaround.
• Manufacturers upgrading to complex multi-axis or newer controllers.
• CAM programmers aiming to reduce manual cleanup and verification time.

The "Pros" (Why shops refuse to upgrade)

• Stability: Many users claim Cimatron E11 is the most stable build in the company’s history. Crashes are rare unless you are working with imported, broken geometry.
• No "Cloud Tax" : Later versions moved toward license servers and subscription models. E11 uses a legacy hardware-locked dongle (Green HASP key). Once purchased, it works forever without an internet connection.
• Post Processor Reliability: The GPP (General Post Processor) in E11, while complex to edit, produced extremely clean G-code. For older FANUC, Heidenhain, or Siemens controllers, E11 is often preferred because it doesn't generate the "nanny code" that modern CAM does.

Step 2: Creating Features

• Extrude: Select a sketch profile. Define direction and height.
• Revolve: Select sketch profile + an axis line.
• Round/Fillet: Select edges. In E11, you can toggle between "Constant Radius" and "Variable Radius" in the wizard.
• Draft: Essential for mold makers. Tilt faces for extraction.
