Telecurso 2000 - Leitura e Interpretação de Desenho Técnico - 17 Omissão de corte

Introduction

This tutorial focuses on understanding the concept of "omissão de corte," or omission of cut, in technical drawing interpretation. It builds on previously learned concepts such as total cuts, partial cuts, and section representations. By the end of this guide, you will be able to identify and interpret elements represented with omission of cut in technical drawings.

Step 1: Understand the Concept of Omission of Cut

• The omission of cut occurs when certain parts of a drawing are not fully represented despite being cut through.
• This technique helps clarify the drawing by avoiding clutter in views where many items are cut through.
• Familiarize yourself with the different types of cuts you have previously learned (total, composite, half-cut, and partial cut) to better understand their differences and applications.

Step 2: Identify Elements Represented with Omission of Cut

• Look for specific features in technical drawings that indicate elements should be omitted in the cut representation.
• Common elements that may be represented with omission of cut include:
  • Parts that are identical to others in the drawing.
  • Areas that do not significantly contribute to understanding the component.
• Use visual cues such as hatch patterns to distinguish between omitted and included cuts.

Step 3: Recognize Orthographic Views with Omission of Cut

• Understand how orthographic views display elements with omission of cut.
• Pay attention to the following:
  • The relationship between different views (top, front, side) and how they interact with omitted elements.
  • The clarity of the drawing in conveying necessary information without overwhelming details.
• Practice interpreting orthographic views by analyzing multiple drawings and identifying where omissions are applied.

Step 4: Practice Interpreting Elements with Omission of Cut

• Review various technical drawings and attempt to interpret the omitted elements.
• For each drawing:
  • Identify which elements are omitted and why.
  • Analyze how the omission affects your understanding of the piece.
• Engage in exercises that require you to redraw a piece with and without omissions to understand their impact on clarity.

Conclusion

In this tutorial, you learned about the concept of omission of cut in technical drawings, how to identify associated elements, recognize orthographic views, and practice interpreting omitted elements. As a next step, review additional technical drawings and apply these concepts to deepen your understanding.
