Automating CAM Software
Through the use of sequences, templates and other time saving devices, it can often be possible to automate much of the manual input and programming of CAM systems.
For example, one might make a template for roughing hard steels, larger than 24 inches, and another for hard steel between 12 and 24 inches, and a third for parts smaller than 12 inches. Similarly, they could have templates (we call them sequences) for other materials, such as Titanium or Zinc, or for other operations, such as finishing or semi-finishing.
Similarly, this approach can be used to automate processes in specialized fields, like Dental.
Dental CAM Milling
First, let us say right off the bat, this works best with open systems rather than closed systems. Not sure what the difference is between an open or closed Dental milling system? We made a small document/presentation outlining some of the differences between an Open Dental CAM Milling system, a Closed Dental CAM Milling system and those in between.
This document can be found at the link here.
Next, you can virtually completely automate the CAM milling process for similar parts, like dental parts, via pre-planned sequences. Simply select a material, select a machine, load parts to mill, locate parts, add support structures and calculate the CAM cutterpaths. If only all CAM programming were that easy.
Why are we bringing this up here you ask? One, all programmers could benefit from some additional automation. Two, Sescoi not only has a WorkNC product for general machining, but also a product specific to dental machining, WorkNC Dental.
In dental machining, you can mill relatively soft materials like Zirconia or Wax, to very hard metals like Chromium Cobalt and Titanium. Parts are usually very small, and often several parts are nested into one block of material.Parts being machined are often scan data, with thousands of points and facets.
In dental machining, finish is important in that you can not have sharp corners and burrs that could cut into the soft tissues of the mouth. Also, of critical importance is what is referred to as the margin. The margin is where the dental prostheses mates with the existing tooth material. This margin must allow for a perfect match else bacteria will get inside and cause decay. Thus the machining must also be accurate, as well as smooth.
The dental industry is often looking for skilled programmers with machining experience. If that’s you, check it out.
