Challenges
Points of the problem faced by the customer
A customer was preparing to begin production of a new workpiece featuring a hexagonal outer diameter.
Since the workpiece would be formed from a cylindrical bar, shaping would require not only milling capability but also a machine equipped with a Y‑axis or B‑axis function.
However, their existing multi‑tasking machines with those functions were already operating at full capacity and could not be allocated to this new job.
They considered assigning the work to a lathe equipped only with turning and milling capability, but without the Y‑axis, they were unsure how the machining could be performed.
Solutions
For this task, Muratec proposed a method that utilizes the "polar coordinate interpolation function."
The function synchronously controls the turret movement axis (X-axis) and the main spindle rotation axis (C-axis) to create contour shapes.
By combining this function with a live tool, it is possible not only to form machine polygons, as in this case, but also to create features such as cutouts and eccentric sections.
You can see the details in the video below.
How did it work to the customer?
By adopting this cutting method, this customer was able to machine the hexagonal profile during the turning process without using the Y‑axis or B‑axis functions.
This approach can also be applied in situations where the Y‑axis stroke is insufficient, helping expand machining possibilities.
Muratec has extensive experience and know‑how in machining applications that utilize this method.
The reference video shown here was filmed in the “Turning Machine Showroom” at our Inuyama factory.
