Glossary of Terms
Collet:
Cone-shaped sleeve that holds an end mill in place in the router or spindle.
End Mill / Cutter:
Cutting tools used by a CNC machine. End mills are similar to drill bits, though, typically
they can cut in all directions. End mills come in several varieties, including square, ball nose, and V-bit, and
many sizes.
G-code:
General, or geometric, code, is a CNC programming language that controls when, where, and how
the machine tools move across the workpiece. For example, when to turn on or off, how fast to travel to a
particular location, what paths to take.
Gantry:
A multi-axis motion system of rails and carriages supported on the sides by, and spanning over, the
baseframe, giving the router overhead access to a workpiece.
Homing:
The process of sending the machine to a known, fixed, repeatable location. This means that every
time you home, the machine will move to exactly the same position allowing you to move your machine to
positions relative to the home position, with great precision. The home position for the Shapeoko Pro is in
the back-right corner.
Job Zero / Job Origin / Toolpath Zero / Program Zero:
It may have many names, but job zero basically tells
the machine where to begin running the job. Job zero is a point in your design where all of the toolpaths
will be based from (the X, Y, and Z coordinates). Job zero is commonly set in the lower-left corner of your
stock.
Jog:
Move the router to a specific position (a set of X, Y, Z coordinates) in the work area.
Stock / Workpiece / Material:
The sheet of material (wood, composite/synthetic, metal) being machined.
Tool Change:
When running a job that require multiple tools, Carbide Motion will prompt you each time
you need to change tools. After each tool change, your Shapeoko Pro will use the BitSetter to measure the
length of the new tool.
Toolpath:
A toolpath is the route the cutting tool will follow as it shapes the workpiece. We use Carbide
Create, Carbide 3D’s cross-platform CAD/CAM program, to define the toolpaths for a project.
Working Envelope:
A working envelope is the CNC machine’s range of movement across each of its three
axes, X, Y, and Z.
Workholding:
These are the options for securing your stock material to the machine table.
Machine‑Use Log
It is good practice to keep a log of machine use so you can track when adjustments are made, fasteners are
tightened, and parts are lubricated. Using your log to track use-time for specific end mills helps determine
when end mills should be relegated to rough work, resharpened, or recycled and replaced. A log is a good
place to keep a checklist of items that need to be inspected or verified before machining. Finally, you can
record all of your project settings and the specifics of each tool chain in your log. You can use the sample
machine-use log on the next page or make one that fits your specific workflow and needs.
