Stock Management

Stock Definition in Manufacturing

Stock serves as the foundational element in the manufacturing process. Before generating toolpaths, it must be precisely defined to represent the raw material’s initial state, which will be machined to meet final design specifications.

Functions of Stock in GO2cam

1. Machining Strategy Planning

   • The software calculates optimal toolpaths based on the stock’s shape, dimensions, and material properties, ensuring precision and minimizing waste.

2. Process Simulation

   • By defining the stock, users can simulate material removal at each stage, helping detect potential machining issues and make necessary adjustments.

3. Efficiency Optimization

   • Stock configuration enables optimized cutting sequences, tool selection, and machining parameters, improving both speed and accuracy in part production.

What is Stock Management?

Stock management in GO2cam uses Parasolid-based B-rep modeling to simulate material removal. The process follows this computational logic:

• 1 NC code block → Generates 1 tool swept volume → Executes 1 Boolean subtraction (updating the stock).

Performance Considerations:

• Large or complex toolpaths may require extended computation time due to accumulated Boolean operations.

• In rare cases, extremely detailed toolpaths can lead to instability or failure.
  

For improved efficiency, Mesh Stock Modelling is available as an alternative to traditional B-rep methods.

Stock Management: "What You See Is What You Get" (WYSIWYG):

• The simulated stock precisely matches real-world machining results.

• Ensures predictable material removal - every toolpath operation modifies the stock exactly as it would on the actual machine.

• Delivers visual truth - the final displayed stock mirrors the physical workpiece after machining.

Stock Management vs. Dynamic Simulation

Stock Display Option

The tolerance of display of the solid and also the stock is defined in Tools / Options / Entities / General / Visual Comfort.(Same settings are accessible via the status bar in the bottom-right corner.)
For accurate visualization and simulation, realistic texture rendering is recommended for the following operations: Tapping Die Threading Thread Whirling Knurling Standard Threading Profile Threading

Rendering Texture of Tapping, Die Threading, Thread Whirling and Knurling are now available in the dynamic simulation!

Display of the Stock in the Program Window

The display of the stock in the machining tab can be controlled with the Filters bar on the right. The transparency state can be controlled by expanding the arrow in top of the stock icon. Use the sliding bar to adjust the transparency level. Check the box to activate the transparent stock, else uncheck it have the stock fully solid and opaque. The Stock icon controls the transparency and visibility states of the stock: Click to hide or unhide the stock. (Note: Unhidden, the stock is visible in the state is initially was which is either transparent or opaque). Scroll-click to activate the transparency of the stock or set is to fully solid and opaque.

The display of the dynamic stock removal during simulation can also be controlled. Click on the link below for additional information:
