The first steps of a beginner CNC programmer
Study the range of parts that your company produces
Get information about the available CNC equipment in your company
Familiarize yourself with cutting tools
You have received the first task from your supervisor to develop a control program for a CNC machine. Take the programming manual for the CNC machine, for example Fanuc, Siemens, NC210. Milling machine 3-axis. Take an additional instruction manual for this machine, there you can see the technical characteristics of the machine. Namely, the maximum spindle speed, maximum working feeds, maximum feeds of rapid movements will be useful to you. You will take all this into account when assigning cutting conditions to create a processing project in a CAM system in which you will generate a control program. Also make the most of the available cutting tools. If necessary, additionally order the missing tool or equipment.
Sketch out the processing strategy in advance, agree on it, and only after that proceed to the creation of a processing project in the CAM system on a computer.
If your company has a CAM system installed, such as Power mill, FeatureCam, SolidCam or others, make sure that there is a working postprocessor for your machine accordingly. What is a postprocessor? The postprocessor is a separately developed software with which you can get a control program for your CNC machine.
Create a setup chart with a list of cutting tools, generate a control program and send it to the shop for implementation.
Here are the main stages of the work of a novice programmer.
