Custom near-net-shape arm segments in heat-treated 4140 steel are intended for agricultural robotics platforms. OEM/ODM manufacturing combines investment casting and CNC machining, with shot-blasting or sand-blasting surface directions. The tolerance reference is 0.1–0.5mm, with the actual controlled dimensions and supplied condition to define for the selected segment.
4140 material condition and the arm geometry
Define the heat-treated material condition and the actual segment shape required for the platform. Identify the important interfaces and component dimensions for that geometry. Relate those requirements to the investment-casting and machining task, agreeing the supplied condition and acceptance needed for the particular agricultural-robotics component.
Near-net-shape casting and CNC interfaces
Select the areas requiring CNC work after casting and define their finished dimensions. Establish where the 0.1–0.5mm reference applies and the measurement criteria for those controlled areas. Connect the cast geometry and machined interfaces to the requested segment, agreeing the dimensional acceptance needed for its actual platform task.
Shot-blasted or sand-blasted surfaces
Choose the surface direction and define the areas covered by the selected treatment. Relate the required finished appearance and condition to the heat-treated 4140 component. Agree the surface and dimensional acceptance after the included work, identifying how those requirements apply to the actual cast and machined arm-segment areas.
Segment inspection and platform requirements
For these heat-treated 4140 arm segments, quality control covers 100% inspection. Define the actual checks and acceptance criteria for the controlled component geometry. Relate them to the selected material condition, CNC scope and blasted surfaces, establishing the supplied-part requirements for the intended agricultural robotics platform and its interfaces.
