: Summary of the effects of rake angle, relief angle, etc. in turning

2020/8/21 Machining/ Foundation

Today's memo is a "Summary of the Influence of Rake Angle, Clearance Angle, etc. in Turning" memo. Image: Borrowed from the reliable Mitsubishi Hitachi Tool Co. The function required of a cutting tool is to ...

: Meaning, reading and conversion of inch dimensions

2025/11/10 How to insert dimensions / Types of dimensions

Today's memo is about "Meaning, Reading, and Conversion of Inch Dimensions." In mechanical design, there are jobs that involve purchasing and using products made in America at the customer's request, or replacing American equipment drawings with Japanese versions and rebuilding or modifying equipment...

: What is the AWG standard for electric wire and what is AWG size?

2020/5/2 Electric wire/Magnet wire

Today's memo is about "What is the wire standard AWG? About AWG sizes." It seems there are slight differences in AWG (American Wire Gauge standard) depending on the wire manufacturer's product line. Therefore, here's how to understand AWG, and examples of wire conductors...

: Sensors, cameras, etc. should have a structure that can be reproduced after adjustment.

2021/7/23 Sensor, Design method

Today, I would like to make a note on the topic of "structure that can be reproduced after adjustment of sensors and cameras". Since many sensors and cameras have a wide installation range, they are often installed with long holes in sheet metal ...

: Alodine (chemical conversion treatment) for surface treatment

2025/10/19 Surface treatment

Today, I would like to make a note on the basic contents of "Alodine (chemical conversion treatment)," which excels in corrosion resistance (rust prevention) and paint adhesion of aluminum. What is Alodine? Alodine is a chromate-treated aluminum ...

: About POM, Duracon, Delrin, Celcon, Iupital, Tenac

2025/10/13 Resin

Today's note is about "POM, Duracon, Delrin, Celcon, Iupital, Tenac". When I am designing a machine, I sometimes see several kinds of materials such as POM in the material designation on the drawing....

: General interpretation of thread chamfer and guide dimensions

2025/8/15 Drawing/Writing

Here is a note on "General Interpretation of Thread Chamfer and Reference Dimensions", one of the notes in mechanical drawing.　This is a little more detailed explanation so that even beginners in mechanical design can easily understand it. Thread chamfer Drawing

: Structural advantages of partial use of articulated robots

2023/12/6 Robot

Today's note is about the structural advantages of partial use of articulated robots, which I have been feeling recently. Structural Advantages of Equipment with Articulated Robots The other day, I muttered something like this. ...

: Surface roughness and surface roughness obtained by different machining methods

2025/8/15 Machining/ Foundation, Drawing/Writing

Here are some notes on "Surface Roughness and Surface Texture Obtained by Each Machining Method". Surface roughness and surface roughness obtained by different machining methods To determine the surface roughness (surface roughness) to be described on a machine drawing, it is necessary to know which machining method is used and which surface roughness is obtained by which machining method.

: 40 Inventive Principles of TRIZ methods that can solve problems and contradictions

2025/10/19 TRIZ, The story of machine design

Today's note is on "40 Inventive Principles of the TRIZ Method for Solving Problems and Contradictions". The 40 Inventive Principles are specific ways to solve "technical contradictions," and they are based on the ...
