3D engineering products are constantly evolving and dramatically changing the manufacturing scene. In particular, the handy type non-contact 3D measuring system (3D scanner) was previously utilized in limited departments, but nowadays it is also utilized in quality control departments and others.

In this article, we would like to introduce a case of Yanagawa Techno Forge (Thailand) (hereafter YTT), a customer of the Japanese affiliated forging industry in Thailand, who implemented a non-contact 3D measuring system at a relatively early stage (in the Thai forging industry).

Yanagawa Techno Forge (Thailand) CO., LTD.
Started hammer forging at their Pathum Thani Plant in Thailand in 1989. As a "forging professional", we perform hot forging of important parts that require strength, such as automobile engine parts.

Forging is a method of manufacturing by heating metal to a high temperature and hitting it, as if making a sword or blacksmithing. YTT uses "hammer forging", which involves applying pressure to die with a hammer, but the die life is short, and it can only be used about 5,000 times, which is 1/10 to 1/20 of casting dies. Therefore, it is necessary to change the die almost every day. In addition, when the die of hammer forging has eccentric die carving, the moment occurs at the impact of hitting then the upper die moves therefore the die design need to take this into consideration in advance. It can be said that it is an industry where the working load on the mold department is high.

Work efficiency has been dramatically improved! A handy 3D scanner implementation case study

Proposals for 3D scanners usually take into account the equipment used at customer’s customer site, the required tolerances, and the product shape comprehensively. YTT installed it twice, first in 2015 and again in 2020.

2015: Installation of the first unit

【Background】
At the request of a Japanese affiliated manufacturer who is a customer of YTT, the full-scale implementation of quality control by 3D shape evaluation was decided.

【Features of Handy 3D Scanner】
■ It is convenient to carry and can measure on the spot without moving the mold.
■ Small size but sufficient accuracy
■ No need to do preparation before measurement

【Results after the installation】
■ It has become possible to measure starting points, intersections, angles, etc., that could not be done before, which is useful for checking the shape in 3D.
■ It has become possible to inspect narrow shapes, R shapes, etc., which were difficult with other measurement tools.
■ Manual modifications of forging dies can be digitized in 3D scanning and reflected in the model, and the history can be saved.

2020: Installation of the second unit

【Background】
At the start of production of new products, there were some shapes that could not be measured by the existing 3D measuring machine (CMM), and there was a further need for 3D shape evaluation. Since the company already knew the convenience of the handy 3D scanner, they had decided to install a new model of the same brand.

【Results after the installation of the new model handy 3D scanner】
■ Work efficiency has dramatically improved due to the evolution of scanning speed and resolution.
■ Rich functionality greatly reduces the time required to correct data after 3D scanning

Example of time saving effect by new model 3D scanner

Work item	Conventional time required	Time required after implementation
Spraying before measurement	15 minutes	0 minutes (spraying not required)
Automatic surface generation	3 hours	20 minutes
Automatic hole-filling	2 hours	10 minutes
Finalize	30 minutes	5 minutes
In addition to the above, various work times have been greatly reduced due to the increase in command functions.

* The time required is a general example and will vary depending on the actual shape and size of the object to be measured. * For our products lineup, please click here Other Product

【Voice of the customer】

Hitoshi Kishino
General Manager
Yanagawa Techno Forge (Thailand) CO., LTD.

“Many of the products we manufacture have complicated shapes, and it could have taken a whole day to measure. After the implementation of the handy 3D scanner, the measurement time had become surprisingly short, and the extra time can be used to create better products. We will continue to utilize 3D measuring systems to create products that satisfy our customers. "
