Mechanism for vertical movement while rotating horizontally

Click For Summary
SUMMARY

The discussion focuses on designing a bespoke machine for aerospace component sampling, specifically a scoop sampler that can extract a 1 mm thick sample. The user intends to utilize a motor-driven shaft connected to a cutter with abrasive particles for effective metal cutting. A key challenge is implementing a mechanism that allows the cutter to move vertically after reaching a depth of 35-40 mm while maintaining horizontal rotation. The user also raises concerns about adapting the design for non-flat surfaces, suggesting alternative mechanisms such as a rapidly reciprocating spoon for effective sampling.

Hi I am trying to make a CAD model of something like the scoop sampler shown below.

http://www.rolls-royce.com/~/media/...tomers/nuclear/scoop-sampling-tcm92-50918.pdf

This is for a university coursework that requires design of bespoke machines. I am trying to design a machine that can literally scoop out a 1 mm thick sample from any aerospace component. My intention is to use a motor to rotate the shaft which is connected to the cutter (with abrasive particles to cut through metal).

See this would initiate the cutting and only cut at the controlled depth (based on the dimension of the cutter) but how can I possibly make the cutter to eventually go up? (lets say after 35 - 40mm length I want the cutter to make a vertical movement so that it scoops out). To clarify I want the final metal scoop to be roughly 40mm long, 20mm wide and max thickness of 1mm. So once it reaches around 35mm how can I make it go up vertically while the shaft and cutter is rotating in the horizontal axis?

Finally what if I don't have a flat surface. Imagine if I have a concave surface. I have some ideas but I can't seem to get through these initial problems.
