In the wooden chair less than one step away from home, I feel the spring.

Hello everyone. It's becoming like spring. Although it is difficult to go out easily these days, I occasionally want to be bathed in the sun. Therefore, while avoiding the crowd, I went to the nearby park.

Look at my original chair.

It's too late to greet you. I'm fabcross writer Asano. Because I couldn't bear to see an ordinary adult male basking in the sun, I did some small projects. Untie the wood tied up with a belt.

The wood is divided into such parts. Put this together like a jigsaw puzzle.

The wooden chair is finished! As soon as you touch the material, you will find the flat cypress solid wood of the cypress, and the ASANO "A" dug out obviously on the seat is also very cute, right?

Contrary to the cute appearance, the intensity is very strong. I weigh more than 80 kilograms and have good support.

Jiang Chuan, a fabcross writer who happened to shoot on the same day, also gave the wooden chair gathered together as a gift. I am very happy that the words on the seat used by Mr. Jiangchuan are written as "E" of EGAWA.

The two sat in a chair together, enjoying a short sunbath and chatting. Although I didn't drink or eat, I felt that I had spent a leisurely time without seeing me for a long time.

Leave the wood processing to the online service.

A wooden chair that performed a beautiful spring time for me. Because it is designed and made by myself, so I am very happy. However, although "done", but most of the work process is handed over to a certain service, I can hardly leave the house to finish the work.

利用したサービスの名前は「EMARF（エマーフ）」。ざっくり言うと、入稿したデータの通りに加工した木材を届けてくれるサービスです。木材版の出前、あるいはネットプリントをイメージすると分かりやすいかもしれません。

Although the existence of EMARF has long been known, it is difficult to have the opportunity to use it. Through this planning, you can experience the experience of obtaining wood furniture at home. As a new use of digital data, please let me introduce it to all fabcross readers.

The digital processing of wood is not as important as 3D printing, and the production of processing data and the operation of equipment require professional knowledge. In addition, because the size of the object to be dealt with is very large, the environment in which the equipment can be used is limited, and the carrying of materials and finished products is also based on the use of cars.

I want to try to make my own wooden furniture. Even if I don't have a processor, I don't have a driver's license. How does EMARF realize my wayward desire? Let me comment on how I used it.

Design, order, can be delivered home in a week!

The utilization process of making furniture with EMARF includes:

1. パーツのデータを作る
2. 加工用にデータを調整する
3. オンラインで発注

These three steps.

まずはパーツのデータを制作します。僕は今回Rhinocerosという3D CADを使いましたが、Adobe IllustratorやAutodesk Fusion 360などの2D/3D CADをはじめ、DXF形式で書き出せる設計ツールがあればEMARFは利用可能です。何もないところから作ると椅子の強度が心配だったので、サンプルとして公開されている「さんかくスツール」のデータを元にアレンジする方法をとってみました。

So far, we will use EMARF functionality in conjunction with regular modeling. You can use easy-to-process commands by adding an EMARF plug-in specifically provided for the CAD type.

One of them is here, the "emAlign" command. As long as you select the entire data to be processed, you can automatically adjust the direction and configure it. Originally, after the end of modeling, I need to put the parts one by one, so I am very grateful for this sense of speed.

Due to the characteristics of the CNC processor, the right corner part needs to be filleted (fillet), which can also be automatically processed by the function of the "emarf" command. I'm happy and relaxed. I don't need to choose one by one, nor do I need to open another software.

Upload the completed data through the send button in the "emarf" command, or load the DXF file exported from CAD into EMARF's service site, as shown above. You can choose the type and size of wood used, as well as whether it is finished (no / deburring / deburring + surface polishing).

After the setup is completed, the processing preview will be displayed after the data is processed in a few minutes, and you can view the material fee, processing fee and finishing fee according to the simulation. The PDF of the quotation can also be issued, which is a happy function for the communication within the company and between enterprises.

This time, two wooden chairs and two flowerpots are made of a piece of 24 mm thick flat cypress wood (1820 mm × 910 mm). The price is 2724 yen (including tax). If you choose cheap materials such as Lacey plywood, a chair can be made of about 3000,000 yen to 5000 yen.

It has been 4 days since we ordered from the website, and the processed wood has been delivered. The delivery time is about a week or so. I am very emotional about the plastic tape with the EMARF logo on it.

All the parts are processed according to the design. Especially the curve part gives people the impression of softness and beauty. Although gaps have been found in small parts, since wood is used, there is nothing we can do about it. Do not do too detailed parts, etc., the design changes can be improved to some extent.

Convenient features that support model design

Machined parts that arrive smoothly like this. The completion of the wooden chair as mentioned at the beginning, let's review the data production process of the flowerpot, another prop that feels like spring, and take a look at the design support function of EMARF.

The flowerpot is made up of five parts, each with a concave and convex pattern. To make the right shape, you can use several commands.

First of all, this way. Under the "emJointHozo" command, orthogonal components appear convex (Hawthorne) and concave (Hawthorne). This is a convenient feature to set the size and number of hosts and automatically create patterns.

This is made with the "emJointAigaki" command, with half of the orthogonal components crossing each other. Because you don't need to deal with models one by one, you can shorten time and reduce design errors.

In the wood cutting process, it is rarely as excessive or insufficient as the size of the 3D model, so the appropriate offset must be set between the components. In EMARF, you can set the value of this offset when you use the "emJointHozo" or "emJointAigaki" commands, so you don't need to modify it later.

In this finished flowerpot, I tried to cover it with dirt and planted flowers. Unexpectedly, the green of the park is also very familiar.

The digital processing of wood is next to it.

こうして無事に、初めてのEMARFでウッドチェアと植木鉢を作ることができました。それぞれかなりシンプルな作りですが、EMARFのサイトでは熟練のユーザーによるハイクオリティな作品も紹介されていますので、ぜひのぞいてみてください。

So, I tried to use a feeling.

Is this a place like this? The overall action is rustling, and the tour guide is also very solid, so you can use it without hesitation. A lot of confusion is caused by the lack of specific experience in the design, so if the surrounding Tips is concentrated, beginners' mistakes will be reduced.

Before the processing quotation is free, if you are interested, please be sure to touch EMARF! The new feeling of wood processing products can be experienced from the data.

Well, I'll run into the sun before I go back.
