4. Plan Machined Surfaces
Surface Ø40h8 and Ø35h9 must be treated according to accuracy and roughness Ra 2.5.
Surface Ø30h7 and Ø40k6 must be treated according to accuracy and roughness Ra 1.25.
Surface Ø40k6 shall be treated according to accuracy and roughness Ra 1.6.
The machining sequence of said surfaces is as follows:
To process such a pin, three incisors will be required: a pass bent with an angle of 900, a pass stop line with an angle and a cut.
A through bent cutter with an angle of 450 can turn the rod in diameter, trim the end surface and turn the chamfer. With a passing stop cutter with an angle, you can turn the rod and trim the ledge.
The cutting cutter cuts the workpiece from the bar.
