Some CAM software has the ability to generate a setup sheet as part of the process of posting g-code. – What does the Part Program expect from the operator? Are there optional stops, messages, #variables to initialize, or other things the operator must pay attention to? This should all be documented in the Setup Sheet for the operator to refer to. – Do we have full information about the workholding in the Setup Sheet and does it match the assumptions of the part program? – Does the setup sheet capture information about Part Zero and any Work Offsets used in the part program?
– Do we have a proper tool list that matches the part program in our setup sheet?
– Are the operations the same and in the same order in both the part program and the setup sheet? In this final step, we’ll verify our setup sheet matches the part program: It’ll will tremendously simplify your life as well as making for far better results. Get yourself a Feeds and Speeds Calculator like our G-Wizard. In surveys, we learned that determining proper Feeds and Speeds is one of the hardest aspects of CNC to learn:Īs someone just starting out, you need a shortcut for Feeds and Speeds. Most CAM and Conversational Software will ask you for this information, and of course you’ll also need it for hand coded g-code. No matter which method you choose to use for your CNC Programming, you will need to be able to determine the proper Feeds and Speeds. Hand written G-Code is most commonly found on lathe programs, which tend to be simpler and more easily hand written than mill programs. Hand written g-code is most often used as an adjunct to the other two when some special behavior is needed or when the parts are relatively simple. Conversational CNC is good for dealing with parts and features of parts that are similar to what would be done easily on a manual (non-CNC) machine. In general CAM has the most power to deal with complex part programs. Deciding which method to use is largely a function of the capabilities of the tools that are on hand together with the complexity of the program to be created. G-Code programs can be created with CAM Software, Conversational CNC, or by hand writing the g-code. Deliverable: Choose CAM, Conversational CNC, or Hand Written G-Code
