When possible, it is better to find a vector file of the image you want to use in your CNC pattern. Someone will want to point out that arcs are also a bunch of lines – well, in this case possibly but CAM software can translate a circle in far fewer lines of code. My simplistic way of describing the difference is this: a raster file is made up of a bunch of dots whereas the vector file is made up of connected lines and arcs. Before the image can be used, all of the graphics need to be converted to a vector file.
The first thing to understand is the difference between a raster file and a vector file. Vector files are easy and ready to go but raster files may take a little work to make them compatible with the CNC software.` Advertisements The Difference Between Vector Files and Raster Files. Many CAD software programs can import an image and help you edit the result. Many people buy images off of the internet to use as a CNC pattern. One way to cheat this lack of talent is to use an existing image file. After several attempts, it becomes just a bit frustrating that my artistic skills are not as good as my imagination makes me believe they are. These include two- to five-axis milling two- to 22-axis turning two- to five-axis wire electrical discharge high-speed simultaneous three-, four-, and five-axis toolpath on-machine inspection (probing) and additive direct energy deposition.įor more information on CAM software, call 80 or visit times I have seen a project that I would like to replicate but just could not get the scale and curves right. The bulk of its current production is dedicated to medical devices, with the remaining amount used for the aeronautics and robotics sectors.ĮSPRIT supports every configuration of CNC machine-from large gantry models and small part Swiss-type lathes, to Swiss-type, millturn, and B-axis multitasking machines-and it enhances a wide range of machining processes. In 2012, the company became ISO13485 certified as a dedicated manufacturer of medical devices. Most of its initial work involved the certification of materials for Airbus aircraft, along with testing many polymers for medical implants. Rescoll was founded in 2001 as a private research laboratory that provides chemical and mechanical analysis and testing of materials. The software also makes it easier for workers in Rescoll’s Methods department to create standard CNC-machining-process programs. This latter capability involves performing process archiving and automatic shape recognition, such as for complex 3D surfaces that require five-axis machining on a milling lathe. anticipate errors and optimize setup time on each machine.”Īfter just a few months, Rescoll dramatically reduced its programming time, enhanced its production and made its CNC machines more intelligent. “We quickly realized that ESPRIT offers a lot of flexibility and possibilities when programming parts. “Our was to integrate and adapt CAM to our entire range of Swiss and three- to five-axis machines,” explains Guillaume.
As a result, the company implemented ESPRIT CAM software (made by DP Technology Corp.) and fully trained Rescoll’s programmers on the software’s turning, milling and multitasking modules.

The company’s standard approach of manual machine programming proved increasingly difficult and unsuccessful for these projects, according to Fabien Guillaume, methods manager at Rescoll. Several years ago, Rescoll management looked into the benefits of using CAM software when it needed to complete projects involving extensive five-axis milling and surface finishing of parts.
