01
What nesting actually does
- Manual marking and cutting versus a nested sheet layout
- Kerf, offcuts and why parts cannot simply touch each other
- Grain direction and when a part may not be rotated
- What the machine can and cannot decide for you

CNC Nesting Operation
From a design file to cut, labelled, sorted parts.
The complete operating course for a nesting machine: what the production file contains, how the sheet is held down, which tool cuts what, and how to tell a good part from a bad one before it reaches assembly.

Who it is for
- Operators taking responsibility for a nesting machine
- Owners deciding whether the Advanced stage is worth it
- Drafters who want to understand what happens to their file
- Comfortable handling full sheets safely with a second person or lifter
- Basic familiarity with cabinet parts and terminology
- No programming knowledge is assumed
What you will be able to do
- Load, zero and run a nesting job from a supplied production file
- Set up vacuum hold-down so small parts stay put through the cut
- Choose the right cutter for the material and recognise when it is blunt
- Diagnose fuzzing, tear-out, burning and stepped edges from the cut itself
- Read a nest for yield and explain where board is being lost
Syllabus
10 modules.
Draft course outline for confirmation. Module order and depth to be finalised with the training team.
02
The production file
- How a cabinet design becomes a panel list and then a machine file
- Toolpaths: cutting, drilling, grooving and pocketing in one file
- Part numbering and how labels tie back to a cabinet
- What to check in the file before you walk to the machine
03
Machine anatomy and safety
- Gantry, spindle, tool changer, vacuum table and dust hood
- Emergency stops, interlocks and safe zones around a running machine
- Personal protective equipment and hearing protection
- Housekeeping: chips, offcuts and trip hazards around the table
04
Vacuum hold-down and the spoilboard
- How vacuum hold-down works and why parts lift or shift
- Zone valves and covering unused table area
- Surfacing the spoilboard flat, and how often it is needed
- Onion-skinning and tabbing for small parts
05
Tooling
- Compression, up-cut and down-cut cutters and what each does to an edge
- Diameter, flute count and cutting length
- Feeds, speeds and chipload in plain terms
- Collet cleaning, run-out and the real cost of a blunt cutter
06
Setting up a job
- Measuring true material thickness, not the label on the pack
- Setting X, Y and Z origin and tool length
- The first test cut and what to measure on it
- Confirming squareness and dimension before running the full sheet
07
Labelling and part identification
- What belongs on a label: cabinet, part, size, edging, drilling
- Label placement so it survives edge banding and handling
- Sorting parts by cabinet as they leave the table
- What goes wrong when labels are applied after the fact
08
Running and unloading
- Monitoring a running job without standing in the wrong place
- Clearing chips and dust between sheets
- Unloading sequence and stacking to protect faces and edges
- Handling offcuts so they are actually reusable
09
Quality control
- Checking dimension, squareness and diagonal on a finished part
- Edge quality: fuzzing, chipping, tear-out, burn marks and steps
- Tracing a defect back to tool, feed, hold-down or file
- Setting an acceptance standard the whole floor agrees on
10
Yield and waste
- Reading nesting efficiency and what a realistic figure looks like
- Where board is lost: trim, kerf, rotation limits, small batch sizes
- Managing and reusing offcuts without losing track of them
- Batching orders to improve yield without delaying customers
