Introduction.- PART I CNC Basics.- Chapter 1 What is CNC?.- Description and CNC defined including the some history. This also might be a good place for the various types of CNC machines.- Chapter 2 DIY-CNC Project Overview Description of the project, tools required and safety. Will include computer requirements.- Chapter 3 Cutting the parts describes the parts layout and special instructions for cutting.- Special instructions for labeling parts for use in later chapters.- PART II The DIY-CNC Machine Chapter 4 - Linear Movement.- Creating the fundamental mechanism for movement with bearings and rails. The reinforcing concept behind this design would be included.- Chapter 5 - Motion transmission.- The translation from circular motion to linear motion using a screw and nut. A bit on the motors and electronics can be introduced here.- Chapter 6 – Joining.- Methods used to join all of the parts to create assemblies.- Chapter 7 - X, Y and Z Axes Relationship This chapter will delve into the intrinsic design principleswith the three axes (How changes to one axis may affect other axes). This chapter can also discuss the importance of reinforcement for larger machine sizes. Chapter 8 - Z-Axis Assembly.- The start of the actual assembly tutorial starting with the Z-axis.- Chapter 9 - Y-Axis Assembly.- The Y-axis assembly is the most appropriate next tutorial since the Z-axis wraps around the main member of the Y-axis. This member/part would serve as the best chapter to chapter transition.- Chapter 10 – Gantry.- The gantry can be discussed here which provides the basis for the X-axis and directly connects to the Y-axis. Also, other motion variations can be introduced here is space permits.- Chapter 11 - X-Axis Table.- Ending the assemblies is the table which is the main partof the x-axis assembly.- Chapter 12 - Affixing the Motors.- Ending the mechanical construction, the motors will be discussed and how these will be mounted.- PART III The Software (the 3 Cs).- Chapter 13 – CAD The first step in the design/cut process. Drawing the part to be cut.- Chapter 14 – CAM.- The second step - providing the various specifications and toolpaths for the drawn part.- Chapter 15 – Control.- The third and final step in the cutting process, inserting the CAM output (g-code) into the control software.- Part IV CNC Sample Projects.- Chapter 16 As space allows.- Chapter 17 As space allows.- Chapter 18 As space allows.- Appendix A - List of parts and suppliers.- Appendix B - Internet resources.
