Building Block 2 of 5

Manual Machining

The hand skills that separate a machinist from a machine operator. A student who has cut a part manually understands what the CNC is doing and why it goes wrong — which is exactly what the next three building blocks depend on.

  • A hand turning the quill of a manual mill to bring an edge finder down onto a workpiece clamped in a vise, with a dial indicator on a magnetic stand reading against the vise jaw.

    Picking up an edge and indicating the vise in

  • A student checking runout on a bar held in a four-jaw lathe chuck, turning the chuck by hand with a key while a dial indicator rests against the bar.

    Manual lathe

    Dialling in a four-jaw chuck to run true

  • A surface grinder with a part held on the magnetic chuck under the wheel and coolant feeding the cut, operated from the table handwheels at the front.

Why it comes before the CNC work

It is possible to teach a student to load a program and press cycle start without any of this. It produces someone who cannot diagnose a bad finish, cannot judge whether a setup is safe, and has no instinct for what a tool is doing inside the cut.

Manual work builds that instinct cheaply and safely, on machines a program already owns. By the time a student reaches Machine Setup, work holding and tool selection are decisions they have already had to make with their own hands.

Assessed the same way as everything else

Each course states its learning objectives and tests against them, feeding the same Skills Learning Objective report an instructor sees for the rest of the system.

Next in the pathway

Manual Machining leads into Machine Setup, where students move to CNC mills and lathes.
