Enhance Your Design Skills with Dimensional Tolerances

In the ever-evolving landscape of engineering and manufacturing, accurate communication of design intent through drawings is imperative. Understanding and applying dimensional tolerances, fit tolerances, and surface property symbols is essential to ensuring the production of quality parts. However, unclear drawings can lead to misunderstandings, resulting in parts being manufactured that deviate from the designer's original vision. This, in turn, can lead to increased costs due to corrections and delays in delivery.

To address these challenges, the IR Technical Education Institute is hosting a public seminar titled "Easy Drawing Techniques: Dimensional Tolerances Edition" aimed at equipping participants with the foundational knowledge and practical skills needed to accurately convey design intent through detailed engineering drawings.

Seminar Overview

The workshop is scheduled to take place on September 3, 2026, offering both in-person and live-streaming options via Zoom. Participants can attend at the Nihon IR Company's headquarters seminar room, with an expected maximum capacity of 16 participants for the physical session. The seminar fee is set at 49,500 yen (tax included) per person, and a recorded session will be available from September 7 to September 24.

Course Objectives

This workshop will cover:
1. The Relationship between Size and Tolerance:
- Understanding the distinctions and applications of standard tolerances based on the revised JIS 2016 standards.
- Assessing prior knowledge through a self-evaluation test.

2. Rules and Techniques for Notating Tolerances:
- Discovering commonly misunderstood rules around tolerance notation.
- Learning about representative mechanical components and associated design techniques.
- Determining tolerance values and considerations regarding upper and lower limits.

3. Fit Tolerances and Surface Roughness:
- An overview of universally applicable tolerance class symbols and their meanings.
- Understanding the significance and notation of surface property symbols.
- Practical design techniques for implementing dimensional tolerances in mechanical components.

4. Fundamentals of Tolerance Calculation:
- Techniques for calculating tolerances within single components.
- Approaches for cumulative tolerance calculations between multiple components.
- Identifying reasons why tolerance calculations may not yield anticipated outcomes.

5. Summary and Evaluation:
- Final self-assessment to reinforce learned concepts through quizzes.
- An open Q&A session for additional clarification and discussion.

Target Audience

This seminar is ideal for:

• - Engineers with 2 to 5 years of experience in design or drafting.
• - Leaders who need to review and provide guidance on drawings.
• - CAD operators and tracers seeking to enhance their skills.
• - Individuals looking to refresh their foundational knowledge in technical drawing.

Why Attend?

With the globalization of manufacturing processes, the need for clear and accurate communication is more critical than ever. Understanding and applying dimensional tolerances properly not only secures product quality but also minimizes rework and enhances competitive cost efficiency.

The IR Technical Education Institute remains committed to providing valuable knowledge and skills through its technical education services, including seminars, e-learning, and training programs tailored for the manufacturing sector.
