What characteristics should be examined when comparing wire types? (Part 1 of 2)

What characteristics should be examined when comparing wire types? (Part 1 of 2)

Jul 6, 2022 | Elements of EDM, General, Wire | 0 comments

This is a great question that applies to both plain brass and coated wires.  When comparing wires, several characteristics and attributes should be examined, especially when trying the first spool of a new wire brand or type. Price alone is not a good...
What’s the best way to create a 4-Axis program to ensure the best accuracy and eliminate wire lines and facetted geometry?

What’s the best way to create a 4-Axis program to ensure the best accuracy and eliminate wire lines and facetted geometry?

Jun 22, 2022 | Elements of EDM, General, Wire | 0 comments

This question hits on many areas that relate to the machine as well as CAM system programming techniques.  Here are a few items to address and review for best results: MACHINE ITEMS: Maximum Taper Angle: It’s important to identify the maximum taper angle that a...
What is the proper programming format for a tapered or 4-axis profile that requires the manual wire threading of an angular start hole on a wire EDM machine?  

What is the proper programming format for a tapered or 4-axis profile that requires the manual wire threading of an angular start hole on a wire EDM machine?  

May 11, 2022 | General, Wire | 0 comments

Angular start holes commonly occur when machining mold tooling lifter pockets and ejector pin details. As part of this process, a position for manual wire threading needs to be determined within the profile, and a M01 Stop Point should be created within the NC...
Can the same electrode reduction undersize amount be used for all electrodes?

Can the same electrode reduction undersize amount be used for all electrodes?

Apr 20, 2022 | Elements of EDM, General | 0 comments

A proper answer requires a detailed look at the overall EDM operation. The practice of using a standard electrode reduction amount is very common, but it might not yield the best Accuracy or Machining Speed results.  Pros of using a common electrode undersize:...
Can I use graphite or copper-graphite electrode materials to machine tungsten-carbide?

Can I use graphite or copper-graphite electrode materials to machine tungsten-carbide?

Apr 6, 2022 | General, Sinker | 0 comments

While graphite materials can be used to machine carbide materials, it is not the best method. One of the reasons is the extremely high electrode wear rate. Burning with a fine-grain graphite, such as DS4 or POCO-3, will lead to 50-60% electrode wear when used to...
