HUST CNC H6D-T Manual
2 - 32
Two programming methods are available for the part program of the numerical control
unit:
Manual Programming
Automatic Programming
Manual Programming
All processes from drawing of the part diagram, machining design, numerically
controlled program algorithm, programming, to the transmission of the program and the
controller are performed manually.
The coordinates and movements of the tool used in machining operations should be first
calculated during the manual programming process. Calculation will be easier if the part
shape is comprised of straight lines or 90-degree angles. For curve cutting, however, the
calculation is more complicated. Both geometric and trigonometric operations are
required for accurate curves. After acquiring the coordinates of the work-piece, create a
complete numerically controlled part program in a specified format using the movement
command, movement rate, and auxiliary functions. Check the program and make sure
that there are no errors before transmitting it to the controller.
Automatic Programming
All processes from drawing the part diagram to transmitting the part program are
performed with a PC.
For complex part shapes, it is both time-consuming and error-prone to calculate the
coordinate values manually, resulting in nonconforming-machined products. To make
use of the high-speed capabilities of the computer, the programmer designs a simple
part program to describe the machine actions and the shape, size, and cutting sequence
of the part, reinforcing the communication and processing capability of the computer.
The input data is translated into a CNC program using a PC, which is in turn transmitted
to the CNC controller via the RS232C interface. This is called the CAD/CAM system
and is used by many units using CNC machines to create a program especially
machining a 3-D work-piece.
