Welcome to IWMS-25 !
It is our great pleasure to cordially invite you to participate in the 25th International
Wood Machining Seminar (IWMS-25 Nagoya), which will be held from Wednesday
through Saturday, October 4-7, 2023, at Portmesse Nagoya (Nagoya International
Exhibition Hall), Japan. The meeting is co-organized by Nagoya University and theJapan Wood Research Society (JWRS).

Concurrently at same venue, the Japan

Woodworking Machinery Association organizes the Japan Woodworking Machinery
Fair with Wood Ecological Technology Fair (Mokkiten Japan/Wood EcoTech). There
are numerous visitors from various industries such as furniture, fixture, woodworking,construction, lumbering, veneer and plywood, environment, forestry, plastic, ecology
and so on from within and outside Japan.
2023 marks the 4th time that IWMS series has come to Japan. For the arrangementof this memorable seminar, we deeply appreciate the major support from the Japan
Woodworking Machinery Association and many companies and associations.
We have a great week planned for you, with substantial technical content, muchopportunity for great social interaction with friends, and for Post-Seminar Tour
participants, the Mokkiten Japan/Wood EcoTech.
We are excited to welcome you to Nagoya, Japan. “Heart of Wood Machining in Japan”
is our motto, symbolizing the location and the emulation of science, stimulating
atmosphere and personal contacts.
Very much looking forward to welcoming you in Nagoya, we remain with best regards.

Satoru Tsuchikawa
Chairperson, IWMS-25

Preface
This is the 25th meeting of a series started in 1963 at the University of California, Richmond,originally named as the Wood Machining Seminar. In the early days, the meetings werebased solely in Richmond, were of modest size, and were specialized solely on wood machining.
For the 9th and subsequent meetings, the increasing success of the Seminars gave confidence
to expand the scope of the discussions to encompass all aspects of wood processing and also todiversify the meeting sites to various centers of wood processing research around the world.
This required a name change and thus the International Wood Machining Seminars were born.
Since then, IWMS meetings have been held in nine different countries, always with strong
attendance and with increasing diversity.
A central and distinctive feature of the IWMS meetings is the strong feeling of community
among the participants, with numerous regulars of many years standing. Thus, in addition
to being a high-level technical meeting, IWMS is also a gathering of both old and newly formed
friends. Strong personal relationships and collaborations are both born and strengthened.
New participants, particularly those at the start of their careers are warmly welcomed. In
this way, the foundations developed by the established generation can be passed on to the newgeneration for them to build on and add their own contributions. It is the hope that they inturn will become regular IWMS participants and encourage the following generation. This
was the dream of the original founders.
Welcome to IMWS-25, welcome to the technical sessions, but most particularly, welcome to the
IWMS community.
With best wishes,

Gary S. Schajer
Chair, IWMS International Advisory Committee
