Interference and Undercutting
Product Code : LSK-TOMLE-10621
Interference and Undercutting (SKU LSK-TOMLE-10621) is a demonstration board showing two gear-tooth faults side by side: interference, where a rack tip jams against the tooth flank, and undercutting, where the tooth root is cut away so the mesh runs freely. It supports gear theory lessons in engineering colleges and polytechnics. Science Lab Supplies produces it at its factory in Saha, Ambala, India and deals directly with colleges, contractors and distributors.
Specifications
The board carries a rack and gear teeth that can be turned in either direction. Turned clockwise, the rack tip is resisted by the tooth flank, showing interference; turned anticlockwise, the undercut teeth let the mesh run smoothly. The listing gives no dimensions or materials, so these are confirmed on the quotation.

Applications and Experiments for the Interference and Undercutting Board
Students rotate the board both ways to feel and see the difference between an interfering mesh and an undercut one. It makes the theory of minimum tooth numbers and the path of contact concrete before learners calculate these limits for real gear pairs in design exercises.
- B.Tech/B.E. mechanical, Theory of Machines: interference in involute gears.
- Machine design: why undercutting weakens small pinions and how it is avoided.
- Diploma mechanical engineering: visual demonstration of gear meshing faults.
- Vocational training equipment for TVET gearing and power-transmission modules.
Standard Scope of Supply
The Interference and Undercutting board is supplied as a single unit as described above. The listing does not detail stands or accessories, so any extras are named on the quotation, which also confirms the board size before the order is placed.
Packing, MOQ and Lead Time
Quotations cover a single board or a set for several lab benches and state packing, delivery time and price for that quantity. Institutes working with a TVET lab equipment supplier often pair it with the involute generation board on one quotation.
As a registered exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Vietnam, Malaysia, Peru, Egypt, Iraq and Nigeria. Send an enquiry from the contact page, build a list in the enquiry cart, or check the lab tender page for tender supply.
Frequently Asked Questions
What is the difference between interference and undercutting?
Interference is when the tip of one tooth digs into the flank of its mate below the base circle. Undercutting is the removal of that flank material during cutting, which avoids interference but weakens the tooth root.
How is the effect shown on the board?
Turning the board clockwise makes the rack tip catch on the tooth flank; turning it anticlockwise, the undercut teeth let the mesh run smoothly.
Is Science Lab Supplies the manufacturer or a trader?
It is the manufacturer. The board is made at the Science Lab Supplies factory in Saha, Ambala, India, so quotations come from the maker itself.
What size is the board?
The listing does not state its size. Ask through the contact page and the quotation will give the dimensions of the board supplied.
