The Inside Diameter Turn Wizard is used to machine an internal diameter (bore) on a lathe using roughing, finishing, and optional spring passes.

Parameter Descriptions

Name

This is the name used to describe the wizard.

It is displayed on the F5 – Conversational page.

Tool No

This is the tool number used to machine the part.

Spindle Spin-Up Delay (ms)

This sets a delay, in milliseconds, after the spindle starts rotating and before machining begins.

Spindle Direction

This setting determines whether the spindle rotates clockwise or counter-clockwise.

Roughing Pass

These parameters define the roughing toolpath:

• RPM
  This is the spindle speed used during the roughing pass.

• Feedrate
  This is the feed rate used during the roughing pass.

• Depth of Cut per Pass
  This is the amount of material removed in each roughing pass.
  The total number of passes is calculated by dividing the total depth of cut by this value.

   

After the roughing pass is complete, the bore remains undersized by the Finishing Depth of Cut (Final) value. This remaining material is removed during the finishing pass.

Finishing Pass

These parameters define the finishing toolpath:

• RPM
  This is the spindle speed used during the finishing pass.

• Feedrate
  This is the feed rate used during the finishing pass.

• Depth of Cut (Final)
  This is the amount of material removed during the finishing pass.

Spring Passes

This sets the number of spring passes to perform.

A spring pass repeats the final finishing cut to remove any remaining material caused by tool deflection under load, which can result in the bore being slightly undersized.

Initial Diameter

This is the starting internal diameter from which the cut begins.

It is located at the centre of the part.

Final Diameter

This is the final internal diameter that the hole will be machined to.

Z End

This defines the Z-axis end position for machining the feature.

Z End is a smaller value than Z Start.

The total machining length is determined by the difference between Z Start and Z End.

Z Start

This defines the Z-axis starting position for machining the feature.

Z Start is a larger value than Z End.

Tool Clearance

This is the distance the tool moves away from the bore as it returns to the starting position for the next cut.

Clearance is always a positive value.

Save

This saves the wizard parameters and returns you to the F5 – Conversational page.

If any parameters are missing or incorrect, MASSO will display and highlight the affected fields.

Cancel

This cancels all changes and returns you to the F5 – Conversational page without saving.

Tab Key Navigation

On MASSO G3, users with an external keyboard can use the Tab key to move through parameters one at a time, reducing the need to use a mouse.
