: 3DCADで設計ミスが激減するからこそ、そこそこの機械を一人で設計出来ていると思った話

2024/3/28 2DCAD／3DCAD

今日は「3DCADで設計ミスが激減するからこそ、そこそこの機械を一人で設計出来ていると思った話」です。今日もタイトルが長めです。先日から、久しぶりに2DCADによる設計 ...

: Things to note about the type generated by the CAD data download service and the notation in the catalog

2020/5/12 General Standards/Recognition

Today's note is about "things to watch out for in the type and catalog notations generated by CAD data download services". I would like to write about a mistake I made the other day in a row.

: Summary of everyone's opinion that machine automation is difficult and has many challenges

2025/11/13 Mechanization/automation

Today, I would like to note the results of a survey I recently conducted on Twitter, "Do you think this kind of service would make it easier for machines to become automated?" I would like to report the results of the survey and provide some additional information. Raw ...

: The work of mechanical design has a sequence of answers somewhere in its conditions. But it is quite difficult to find it.

2023/12/2 The story of machine design

Today, I have a super sympathetic note about "There is an order to answer in the mechanical design work in its conditions somewhere. But it's pretty hard to find it. I was reading an article that resonated with me ...

: How to calculate torque from kW (rated output) of motor

2025/8/23 Motor

Here is a note on "How to calculate torque from kW (rated output) of a motor", knowledge that is sometimes necessary when selecting a motor. When designing a machine, power is sometimes expressed in kW ...

: The following is a summary of ball screw materials from each manufacturer for your reference.

2024/1/20 Ball screw

Today's note is about "Ball Screw Material Summary of Each Maker". The other day, I had a chance to use Power Lock for THK's ball screw (shaft end), and at that time, I needed to check the material (strength) of the ball screw shaft.

: Anti-resonance/vibration couplings

2020/5/2 coupling

Today's note is about "anti-resonance/vibration couplings". Many of you already know about this, but I thought it was "great" again at a recent job I was involved in, so I thought I would share it with those who are suffering from resonance/vibration in equipment that handles servos, and especially those ...

: Calculation of approximate circumference of timing belt and distance between shafts

2020/7/26 timing belt

Today's note is on "Calculation of Approximate Circumference and Distance Between Shafts of Timing Belts". This is a formula that you can use when you assume the distance between shafts of a timing belt during the design process. In addition, this article is about "Calculating the approximate circumference and axial distance of a three-star belt (tie ...

: Machined parts after welding, flat machining near a wall is basically no good unless it is away from the wall.

2025/11/13 Welding

Today's note is "The basic rule of thumb is that machined parts after welding and flat machining near a wall must be away from the wall. I'm not sure if this title is appropriate and communicates well, but this is what I was inquired about by a machinist, and I told the design engineer and ...

: Thrust force table and formula for hydraulic cylinders

2020/9/9 Security

Today's memo is about "Thrust Force Table and Thrust Force Formula for Hydraulic Cylinders". Unlike air cylinders, hydraulic cylinders have a higher pressure setting in the hydraulic circuit used and have a very large thrust force. Today, we will create a table that shows the thrust of the hydraulic cylinder ...
