Understand machining. Make informed decisions.

Climb and conventional milling

Distinguish cutter rotation, workpiece feed and chip formation, then consider the machine before choosing the direction.

Milling: engagement and feed

Understand depth of cut, radial engagement and feed per tooth instead of choosing a milling process by spindle speed alone.

Turning: geometry, chips and finish

Distinguish longitudinal turning, facing and grooving, then select tooling from the actual machining task.

Cut tapping or form tapping?

Two ways to make internal threads: remove material or displace it. Pre-hole size and material suitability are essential.

Tap geometry: flutes and chamfers

Understand spiral flutes, spiral points and straight flutes by asking where the chip can safely go.

Drilling: tool selection and chip evacuation

Consider diameter, depth, runout and coolant together so that chips do not become a process risk.

Selecting cutting tools systematically

Work from the component to the tool, considering cutting material, geometry, holder and cost together.

Workpiece materials in machining

Why material grade, heat treatment and hardness tell you more than broad names such as metal or stainless steel.

Understanding tool coatings

Coating is one part of the tool system. Colour and coating name alone are not enough for selection.

Recognising tool wear and edge damage

Separate the observed damage, possible cause and corrective action: one photograph is not a confirmed diagnosis.

Thread milling: path, feed and inspection

A rotating thread mill creates the profile along a helical toolpath.

Cooling, lubrication and chip evacuation

Choose dry machining, cutting fluid or MQL for the actual operation.
