CNC System Instruction
8.2. Selection of Pattern Elements
So far, this system provides 24 pattern elements, which is expandable at any time as per client requirement. It is al-
lowed to select the interested pattern by pressing
[↑], [↓], [←]
and/or
[→]
key to move the cursor to right position and press
[ENTER] to acknowledge the selection.
Note: The 17th pattern element is customized element.
8.3. Ar\rangement and Layout of Pattern Element
After pattern element is selected as per the above
-
mentioned procedure, the system will prompt at the upper right corner to
input parameters for the pattern, as show in Fig. 13.2
【
F1
】
Workpiece:
To machine into workpiece that is solid internally.
【
F2
】
Hole:
To machine into hole that is solid externally.
【
F3
】
Rotate:
The system will prompt to input rotation angle and press [ENTER] or [F6] to acknowledge. The pattern
rotated such an angle will appear. Counterclockwise direction is taken as positive angle.
【
F4
】
Layout:
The system will prompt user to provide:
Row number
----
Row number of machined parts array
Column number
----
Column number of machined parts array
Row pitch
----
Distance between rows.
Column pitch
----
Horizontal distance between machined parts
Row offset
----
The deviation of raw misplacement, as shown in Fig. 8.3.
【
F8
】
Submit:
After parameters are set, press this key to generate machining program.
8.4.
User Defined Module
User is allowed to customize module with the following method .
Firstly, it is required to edit a standard program for the self
-
defined module and name it as TK17S.NC, which should have
the following structure:
G92 X0 Y0 // User
-
defined module, Note: The original program should not have more than 59 lines.
G28 // The last line should command the torch to return to the reference point.
M02
Simply copy this program into the file system. The 17th pattern element is self
-
defined. If no new module is self
-
defined, the
system will take the old module automatically.
This module is allowed to use for Layout and Rotate features, but no parameter to set.
