1. Tasks related to setup and operation – In this lesson we introduce the tasks related to making setups and running production. Included: tasks required for setting up machining centers in the approximate order setups are made and tasks required to run production.

2. Machine configurations – It is important for setup people and operators to understand the makeup of the machine they work on. Included: Components, directions of motion (axes), controllable functions, and buttons & switches.

3. Workholding setup – Workholding setup is an important setup-related task. Included: the machine table, workholding devices, aligning workholding devices with the machine table, and assigning program zero.

4. Cutting tools – There are several cutting-tool-related tasks that must be completed during setup. Included: understanding cutting tool components, gathering, assembling, and entering cutting tool components, entering offsets, and sizing and trial machining.

5. Running the first workpiece – Setup includes running the first workpiece. Topics include: loading the program, verifying the �lementary� of the program (new programs), considering what each tool will do, and re-running tools.

6. Completing a production run – Completing a production run involve many of the same tasks done during setup. Included: Optimizing the job, tasks related to the production run, running one workpiece, sizing adjustments, and replacing dull tools

1. Understanding parameters – All CNC people should be aware of how parameters affect how CNC machine tools behave. Included: Introduction, eight bit binary type, whole number type, how parameters affect machines, backing up.

2. Documenting in the program – All CNC programmers should include adequate documentation within the programs they write. This lesson discusses the most important times when documentation should be included in the program.

3. Block delete techniques – Block delete (also called optional block skip) can be used when you want to give the operator a choice between one of two possibilities. Included: using block delete mid-command, trial machining, allowing for exess stock, and �lementa block deletes.

4. Techniques with sequence numbers – While sequence numbers (N words) are extremely �lementary CNC words taught in every basic CNC course, there are some advanced implications of their use. Included: identifying restart commands, statement labels.

5. G code commonalities – G codes share certain things in common. In this short lesson, we explore commonalities. Included: maximum number of G codes per command, monitoring current G codes, setting initialized states.

6. Techniques with motion types – The basic motion types (G00, G01, G02&G03) are usually well covered in basic courses. There are, however, some techniques we’d like to relate. Included: G00-G01 for positioning, which is faster G00 or G01?, techniques with circular motion.

7. Special motion types – Control manufacturers provide special interpolation types for special applications. These motion types are seldom covered in basic courses. Included: helical interpolation, spiral interpolation, cylindrical interpolation, polar coordinate interpolation.

8. G04 – dwell techniques – The dwell command is used to cause axis motion to pause for a specified period. It may not be mentioned in some basic CNC courses. Included: dwell period options, relieving tool pressure, programming around machine problems, exact stop check.

9. G10 data setting command – G10 can be used to program data entries (offsets, parameters). It is rarely discussed in detail during basic CNC courses. Included: how G10 works, tool length and cutter radius offsets, tool nose radius offsets, work shift values, parameters.

10. Plane selection G17, G18, & G19 – Plane selection commands are used (especially on machining centers) to tell the control whether the program will be machining in the XY, XZ, or YZ plane. Included: right angle heads, circular motion, canned cycles, cutter comp.

11. Inch / metric selection – Most current model CNC machine tools allow you to work in either the inch (English) or metric system. Measurement system modes aren’t discussed in most basic CNC courses. Included: Switching, advantage of metric mode, what happens when switching.

22

12. Motion manipulation techniques – There are several special CNC words that can be used to manipulate the way the machine will perform motions. Included thread cutting, polar coordinates, scaling, mirror image, coordinate rotation.

13. Radius compensation G40, G41, & G42 – While this feature is covered in most basic CNC courses, most barely scratch the surface of what is possible, and most do not warn you about potential problems. Included: two ways to use, handling problems, limitations, programming offset entries.

14. Tool length compensation – While tool length compensation is well covered in most basic CNC classes, there is one special technique that is not usually discussed. Included: using secondary offsets, if mistakes are made.

15. Spindle limiter G50 – While some basic CNC course mention G50, there are several things that are not discussed. Included: How G50 works, chuck changes, changing parameters to set max speed, with bar feeders
