Inside Diameter Turn Wizard

The ID Turn wizard bores an internal diameter on a lathe with roughing, finishing and optional spring passes.

Applies to

MASSO G3 and G3 Touch – Lathe

Passes

Roughing, finishing, spring

You need

An existing hole to start from

CAUTION

This wizard doesn't add safe tool change positions for automatic tool changers. Check the generated G-code before running so the tool moves clear before each change. Manual tool changes aren't affected.

Tool and spindle

Field	Parameter	Description
	Name	Describes the wizard; shown on the F5 – Conversational page.
	Tool No	Tool number used to machine the bore.
	Spindle Spin-Up Delay (ms)	Wait time after the spindle starts, before cutting begins.
	Spindle Direction	Clockwise or counter-clockwise.

Passes

Roughing pass

RPM	Spindle speed for roughing.
Feedrate	Feed rate for roughing.
Depth of Cut per Pass	Material removed per roughing pass. The number of passes is the total depth of cut divided by this value.

After roughing, the bore is left undersize by the finishing Depth of Cut (Final), which the finishing pass removes.

Finishing pass

RPM	Spindle speed for finishing.
Feedrate	Feed rate for finishing.
Depth of Cut (Final)	Material removed by the finishing pass.

Spring passes

Number of spring passes. A spring pass repeats the final cut to remove material left behind by tool deflection, which would otherwise leave the bore slightly undersize.

Bore and dimensions

Field	Parameter	Description
	Initial Diameter	Starting internal diameter: the existing hole at the centre of the part that the cut begins from.
	Final Diameter	Finished internal diameter of the bore.
	Z Start	Z where cutting begins. Must be larger than Z End.
	Z End	Z where cutting ends. Must be smaller than Z Start. Z Start − Z End is the bore length.
	Tool Clearance	Distance the tool backs off from the bore wall when returning for the next cut. Always positive.
