You automate drawer box production by linking the steps into a cell: sizing the parts, cutting the dovetails on a CNC dovetailer, machining the bottom groove, and gluing/clamping/squaring the box on an automated clamp — with material handling between stages. This replaces a labor-heavy, skill-dependent bench process with a fast, consistent line that handles mixed sizes from stored programs.
Before the machinery, understand where the labor actually goes. Because it isn’t where most people assume.
Where the Labor and Time Actually Go Today
It’s the handling.
The manual drawer box process involves repeatedly handling every single piece to cut the mortise and the tenon. Pick it up, position it, cut, set it down, pick up the next one. It’s intensely repetitive, it’s physically wearing, and it consumes a person for a whole shift.
Then there’s the part nobody puts in the business case. A skilled operator can “get good” and hit the 80 drawer parts an hour a Mereen-Johnson 1105 is capable of. Most operators don’t — because woodworking facilities have high turnover, and the person who got good left.
So your real throughput isn’t the machine’s ceiling. It’s the running average of every person who has ever stood in front of it, weighted by how long each of them stayed. That’s the number automation actually replaces.
The Five Stages of a Drawer Box Cell
| Stage | What happens | What automation changes |
|---|---|---|
| 1. Sizing | Sides, fronts, backs cut to dimension | Feeds the cell consistently sized stock — the prerequisite for everything downstream |
| 2. Joinery | Dovetails cut on mortise boards (ends) and tenon boards (sides) | The biggest labor block. Where most shops start. |
| 3. Bottom groove | Dado for the drawer bottom | Often combined; must be registered off the same reference |
| 4. Assembly | Glue, clamp, square | Automated box clamp/press |
| 5. Handling | Moving parts between all of the above | The glue that turns four machines into one cell |
Step 1 — Sizing the Parts
Nothing downstream works if the parts aren’t consistently sized. A dovetail machine is precise; it can’t correct for stock that arrived wrong.
Sizing is the least glamorous stage and the one that quietly determines whether the rest of the cell delivers. If your sides, fronts, and backs vary, you’ll spend the savings from automation on rework. Sizing machinery →
Step 2 — Cutting the Joinery
This is the big one, and it’s where the labor is.
A CNC dovetailer machines the joint from a stored program. The Model 1105-H — 5 HP driving five spindles, dual cutting path to virtually eliminate tearout, cutter compensation for joint-fit adjustment, automatic partial tenon removal — is the production machine, capable of drawer parts for 80 drawers per hour. The Model 1101 single-spindle machine trades some speed for joint variety and short-run flexibility.
Through dovetails go on drawer sides; half-blind dovetails on finished drawer fronts. Both are exceptionally strong when properly machined — the choice is aesthetic.

Step 3 — The Bottom Groove
The dado that carries the drawer bottom. Straightforward machining, but with one thing worth getting right: it has to be registered off the same reference as the joinery. A groove that’s 1/32″ off relative to the dovetails produces a box that won’t sit square, and you’ll discover it at assembly rather than at the machine that caused it.
In a cell, that reference is maintained mechanically rather than by an operator remembering which face was up.
Step 4 — Assembly: Glue, Clamp, Square
Machined parts become a drawer box here. Glue is applied, the box is clamped, and it’s squared before the glue sets.
An automated box clamp or box press does this consistently — and the ergonomic layout of a dovetailer + box press work cell is a well-established, high-production pairing.
We won’t go deep here, because clamping deserves its own treatment. Box clamps & box presses →
Step 5 — Material Handling: What Makes It a Cell
Four automated machines with people carrying parts between them is not a cell. It’s four machines and a lot of walking.
Handling is what closes the loop, and it’s where the RDT1020 changes the conversation entirely.
The RDT1020: no-operator dovetail production
Mereen-Johnson’s RDT1020 is the industry’s first fully integrated, no-operator dovetail production cell. It combines AI-based 3D machine vision, a 6-axis industrial robot, and the 1105-H dovetailer to autonomously produce both mortise boards (drawer ends) and tenon boards (drawer sides).
What it does with no one standing there:
- Depalletizes raw boards
- Identifies and orients each part with AI-driven 3D vision — no precise pre-staging, no manual alignment required
- Machines the dovetail
- Re-palletizes finished components
- Manages slip sheets and variable board geometries on its own
The human involvement is pallet changeover. That’s it — typically every 4–8 hours depending on load size. Remove the pallet of finished parts, add a pallet of new parts to cut.

The throughput insight that surprises people: the dovetail machine is capable of 80 drawer parts per hour, but the automated cell doesn’t need to run that fast to beat a manual operation — because it never slows down and never takes a break. Consistency beats peak rate over an eight-hour shift, every time.
Optional barcode scanning and AGV/AMR integration extend the cell toward lights-out manufacturing.

Mixed Sizes and Quick Changeover
The standing objection to automating a mixed-size, custom-heavy drawer operation is that automation will slow you down.
It won’t, and the reason is that the flexibility moved into software.
On a CNC dovetailer, pitch, size, pattern, and part thickness all change in seconds from the operator console. Joint fit is adjusted through cutter compensation. Programs are saved and recalled. Once a drawer size exists as a program, it exists forever.
The operator isn’t rebuilding the machine. They’re loading the next job.
And in the RDT1020, the AI 3D vision system handles variable board geometries without precise pre-staging — meaning the cell tolerates the messiness of real mixed production rather than demanding perfectly presented stock.
Labor, Throughput, and Consistency
| Manual | Automated cell | |
|---|---|---|
| Throughput | 2–8 drawers/hour (manual dovetailing) | Never stops; machine capable of parts for 80 drawers/hour |
| Labor | Continuous operator handling every piece | Saves 1–2 people depending on the operation |
| RDT1020 specifically | 1+ dedicated operator per machine | Frees ~2 operators per shift for higher-value work |
| Operator involvement | Constant | Pallet changeover every 4–8 hours |
| Consistency | Varies with skill, fatigue, and turnover | Repeatable; reduces variability and rework |
| Safety | Constant human contact with cutting tools | Minimal interaction with moving machinery |
Note the framing on labor. In most shops this isn’t a headcount-reduction story — it’s a headcount-you-couldn’t-hire-anyway story, and a redeployment story. The two operators the cell frees go do something that needs a human.

Retrofit vs. Turnkey
Automate around your existing equipment. Depending on your plant floor space, we can build a robotic cell around a 1105 dovetailer you already own. If the machine has useful life left, use it.
Build a purpose-designed cell when footprint, throughput, or integration with the rest of your line justifies it.
What customers underestimate
Two things, consistently:
1. Footprint. A cell needs room — for the robot’s reach envelope, for infeed and outfeed pallets, for a technician to get at the machine. It’s more than the machine plus a robot arm.
2. Integration with the rest of the line. This is the bigger one. Shops plan the dovetail cell carefully and then discover they haven’t thought about how it hands off to box assembly. A cell that produces machined parts faster than the assembly stage can consume them just builds a bigger pile of machined parts.
The rule: plan the handoffs before you plan the machine.

ROI and Payback
Typical payback on a dovetail cell: 2–3 years.
The math is driven by:
- Labor saved — 1–2 people, or ~2 operators per shift with the RDT1020. Multiply by shift count and fully loaded cost.
- Throughput — a cell that runs unattended for 4–8 hours between pallet changes.
- Consistency — less rework, fewer rejected boxes, fewer joint-fit callbacks.
- Turnover — the cost nobody spreadsheets: the scrap and ramp time every time your good operator leaves.
Frequently Asked Questions
What are the steps in automating drawer box production?
Sizing the parts, cutting the dovetail joinery, machining the bottom groove, gluing/clamping/squaring the box, and material handling between each stage.
Which step should I automate first?
The joinery. It’s the biggest labor block — the manual process requires handling every single piece to cut the mortise and tenon — and it’s the most skill-dependent step in an industry with high turnover.
How many people does an automated drawer box cell save?
1–2 people depending on the operation. The RDT1020 no-operator cell frees approximately two operators per shift.
How much throughput can an automated cell hit?
The Mereen-Johnson 1105 dovetailer is capable of drawer parts for 80 drawers per hour. In practice the cell doesn’t need to run at peak rate to beat manual production, because it never slows down and never takes a break.
Can I automate around my existing dovetailer?
Often yes. Depending on plant floor space, a robotic cell can be built around an existing 1105.
How does an automated cell handle mixed drawer sizes?
Through software. Pitch, size, pattern, and thickness change in seconds from the console, and programs are saved and recalled. The RDT1020’s AI 3D vision handles variable board geometries without manual alignment.
What’s the payback on automating drawer box production?
Typically 2–3 years, depending on operation size, shift count, and labor cost.
What do customers most underestimate?
Footprint, and how the cell will integrate with the rest of the line — box assembly especially.
