Q: Is there a way to graphically show the M01 or M00 stop points in the program graphic on my U3 machine with the Hyper-i control?
A: Graphically displaying M01 and/or M00 stop points is possible on the Hyper-i control, but may require you to perform a software upgrade. Hyper-i version 10 and higher provides the ability to display icons on the NC program graphic display, including icons for wire thread, wire cut, and stop points (M00, M01, M08). The icons can be displayed on both the PROGRAM and RUN page Graphic Check screens, and can be activated using a check box menu on the Graphic Settings screen.
Q: What type of graphite should I be using for general machining applications?
A: There are many different grades of graphite that are available, and each type is designed with a specific set of characteristics that change the performance attributes and cost of the material. Selecting the proper grade of graphite material is critical to your operations, and can help boost machine performance while managing your material costs. The graphic provided below from VersaGraph outlines several different grades of graphite with an overview of their characteristics and ideal applications. If you have specific questions about selecting the proper grade of graphite, please leave us a comment below.

Keeping a wire EDM running at peak performance requires proper maintenance and the appropriate consumables for the job. After evaluating the myriad of filter options available on the market in 2017, authors at the EDM matters blog recommend that EDM shops check out the Mann+Hummel wire EDM filters. These filters offer a variety of advantages to help improve EDM operations:
Q: What is the different between the circular and square orbit patterns, and which one should I be using?
A: All CNC sinker EDM machines feature a selection of different orbit patterns, but circular and square patterns are the most common. The purpose of an orbit pattern is to enlarge the size of the final cavity while maintaining control of the shaped geometry. Use of a circular or square orbit pattern will affect the shape of the final produced cavity differently, so the selection of one type over the other is strictly dependent on the shape of the electrode and the specific geometry requirements of the final work piece. The use of a wrong orbit pattern may result in incorrect radii size or the machining of unwanted flats in the final part.
The circular orbit pattern is the most commonly used. This pattern increases the size of the electrode geometry uniformly on all sizes, but will increase the size of any internal radii. When using a circular orbit with a square or rectangular electrode, the produced internal radii size in the corners will be increased and be larger (Overburn + Orbit Amount).
A square orbit pattern increases the size of the electrode geometry uniformly on all sizes, and will produce the smallest possible inside corner radii. When using a square orbit with a circular electrode, there will be (x4) flats produced. These flats will occur at the X/Y quadrant points, and the size of the flats will be equal to the size of the orbit pattern amount.
Makino sinker EDM machines also feature many other canned cycle orbit patterns that address the needs of 2D and 3D orbit patterns and special electrode shapes, which will be covered in a future Q&A.
