Through this section, you can quickly know the following machining processes for
Integrated CNC System for Shoe Molding Machines:
1. Load a program file.
2. Select tools for machining.
3. Execute selective machining.
4. Do the related setting for machining.
5. Adjust the WCS.
6. Calibrate after tool changed.
2.1 Load a Program File
A shoe mold has multiple faces, and each face corresponds to a program file.
To load program files, do one of the following:
•To machine one face of a shoe mold, load a program file from the following path:
–The host: Program files saved in the root directory of the host
D:\\NcFiles.
–A USB flash disk: Program files saved in the root directory and
subdirectory of the USB flash disk.
–The internet: Program files saved in the host or the network.
It is similar to load a program file from these three paths. This section takes
Load a Program File from the Internet as an example.
•To machine the whole shoe mold at a time, set a machining task and load all
program files.
2.1.1 Load a Program File from the Internet
This operation is used to establish network connection between the integrated CNC
system for shoe molding machine and PC, to realize two-way transmission between
them.
To load a program file from the internet, do the following:
1. Set the IP address.
2. Verify the connection.
3. Access a shared program file.

2.1.1.1 Set the IP Address
This operation is used to establish the network connection channel between the
integrated CNC system and the PC by automatically obtaining or manually setting
the IP address.
It is default to automatically obtain the IP address. And this operation takes
manually setting the IP address as an example.
Before setting the IP address, ensure that the integrated CNC system and PC are in
the same subnet.
To manually set the IP address, do the following:
1. Press → 2→ F1. Network Setting dialog box pops up:
2. To not automatically obtain the IP address, press .
3. Press ↑or ↓to select the target input box, and set the following addresses:
–IP address
E.g. 192.168.1.188 (the first three digits should be the same with that of
PC, and the last digit should be different from that of PC)
–Subnet mask
It is the same with PC.
–Default gateway
It is the same with PC.

2.1.2 Set a Machining Task
The system can automatically match the program files with technics and load all
matched program files at a time to improve efficiency.
To machine several faces of the shoe mold with one tool at a time, set the machining
task and then machine the shoe mold with the selected tool.
The default matching rules of program files with technics, workpiece coordinate
systems and A-axis coordinates are as follows:
Number
