Homework 1 (Metal Cutting)
1. a. FANUC ROBONANO has 5 axes: X, Y, Z, B, C. The axes of this machine are divided
into stages with B and X axes and stages with Y, Z, and C-axis.
When looking at this machine from the front, the axis that moves horizontally is
the X-axis. This stage also has a B-axis that rotates when viewed from the top view.
The other stage has Y, Z, and C-axis. First, when looking at this machine from the
front, the axis that moves vertically is the Y-axis. This stage can move back and
forth, the axis being called the Z-axis. This stage also has a C-axis that rotates when
viewed from the front view.
b. DMG MORI NT-1000 originally has 10 axes: X1, X2, Y, Z1, Z2, A, B, C1, C2, BW.
There are 3 stages in this machining center. However, in this semester, we only have
5 axes: X1, Y, Z1, C1, B. This is because our machine detached the right rotational
stage which has A, BW and C2-axis and the below moving stage which has X2 and
Z2-axis. Therefore, there is one left stage which contains X1, Y, Z1 and B-axis. C1axis is attached the basic DMG MORI NT-1000 and rotating around the Z-axis.
When viewed from the front view, the horizontal moving axis is the Z1 axis, and
the vertical moving axis is the X1 axis. This stage can move back and forth, the axis
being called the Y-axis. Moreover, B-axis rotates around the Y-axis.
2. “Smart Manufacturing” is about autonomy, evolution, simulation and optimization
of the manufacturing enterprise. According to the Andrew Kusiak, Smart
manufacturing is not just a matter of automation. Moreover, it has six essential
parts manufacturing technology and processes, materials, data, predictive
engineering, sustainability and resource sharing and networking [1].
The important parts of it are networking and data. The rapid development of the
IoT in recent years has made it possible to transmit data wirelessly and use AI to
analyze data much more efficiently. To be specific, the speed of 5g wireless
networks has surpassed that of wired networks. This means that it became possible
to transmit data received from existing sensors wirelessly rather than wired.
Therefore, it became possible to obtain new data by installing a wireless sensor in
a place where a wired connection was impossible.
