Object-Oriented NC code

Advantages of Object-Oriented NC code:

• Object-oriented programs are well structured, which makes it easy to figure out what a particular routine does.
  
  
• With object-oriented programming files are easy to edit on the wire machine saving valuable production time. For example, the order in which the different objects are cut may be changed.:EPack settings, offsets, object taper angle, micro-joint settings, or just running one cut of the ten different cuts in the job.
  
  
• Object-oriented programs are easy to test. The whole job may be broken down into smaller components and isolated to testing specific components.

 

The basic idea of object-oriented programming is simple. Data, and the routines to process the data, are separated sorting the processing routines, called control blocks, to the top of the file, and the data blocks to the bottom of the file.
Each control block sets up the wire machine to run a data block in a different way. One control block could set up the rough cut with a taper, Z1 & Z5 setting, micro-joint, EPack, feed rate, and offset. A second control block could access a different data block to cut off the micro-joint. The next control block could cut a skim or even cut the land cuts all with the first data block. By allowing different control blocks to access the same data block, you save memory space, processing time, and time to try to edit the old style code are all saved.

The Output file is divided into 4 distinct groups. Each group plays a significant role in the operation of the file.

Header:

• Tells the wire machine:
  • the file number
  • file name
  • units of measure
  • machine start location
    
• Gives the operator key pieces of information
  • date the file was created
  • the disk file name
  • the original AutoCAD file name
  • the programmer's name that created the file
  • machine type file was created for
  • EDMwire version number

Sets the parameters and controls the sequence of events for the data blocks to be executed.
