2.1 Operation Devices Type
The control panels can be divided into two units: MDI and OP. The MDI is used to edit part
programs as well as to enter relevant working data. The OP (Operation Panel), on the
other hand, is used to manipulate operational conditions. There are multiple function keys,
keys and pulse generator (hand wheel) and etc. OP will have different designs due to
different tool machine designs. But, this system has one standard panel that can be
selected by tool machine producers. MDI will be introduced in the following. OP and its
functions will be introduced in Chapter Three.

2.5.7 DNC Function
DNC function is a very useful function for CAD/CAM system users, especially the
controller is the controller used only (not the controller of PC BASED). Since the storage
memory capacity is not very big, so not possible to download all the programs at once,
which implies that it is very important for the DNC function to do its function while
transmitting. Since DNC program is doing its function while transmitting, so the controller
can’t edit it, neither using program calling nor using jump commanding. LNC Technology
Co., Ltd. already installed high capacity hard drive, therefore, users can transmit files into
the hard drive and then execute those files (this method is called the internal DNC method.)
The DNC function of executing its functions while transmitting is the other DNC method
(this method is called the external DNC method.) The above methods are very
convenience to use. The procedure is as below:
1. To set Controller and external PC as RS232 modal and to set the communication
protocol the same
2. To switch to EDIT mode
3. To press function button【COMM】in order to enable file windows and to set file
name as RS232
4. To switch to AUTO mode
5. To press “CYCLE START” button on OP Panel in order to transmit CNC waiting
program
6. To enable external PC to do RS232 file transmitting
7. To execute machine work automatically

2.7 Milling EASY-CAM
2.7.1 Preface
This function provides 2D pocketing work of one allowable island. The function area has
「Rough-Cutting」and「Fine-Cutting」working types. The CAM function in this controller
allows users to produce auto NC path for its pocketing of any Profile shape. It means that it
can define working piece’s geometry shape direction on the controller. Also, it will produce
the corresponding post NC code after setting the related working parameters.
2.7.2 Function Specification
Since this is a CAM system that is built inside the controller. In order to get the actual
balance of the calculation efficiency of the specification, there are some using restrictions
as below:
Only allow defining one closed Profile and it is limited inside the closed Profile. Only
can define maximum 6 islands.
The line/arch’s number of elements that are made by a single close profile and island
cannot be more than 100 sections.
Elements that are combined by Profile and Island must be closed.
Island must be surrounding by Profile. So, the island must be defined with the Profile.
Cannot have any intersect or self-intersect between islands. Also, cannot have any
