Mill - Turn Introduction

WHAT IS MILL -TURN?

Mastercam Mill-Turn combines the power of Mastercam's Mill and Lathe toolpaths with a suite of tools andtechnologies that let you program advanced multi-function, multi-stream lathes and machining centers.Mill -Turn machines consist of machines with Upper and Lower Turrets, B-Axis Heads and Lower turret andB-Axis Heads

The Mill-Turn platform has specific license requirements depending upon the complexity of the machinesbeing programmed and the user access level Mastercam Mill-Turn is a set of tools and features which runs

on top of Lathe It uses licenses differently than other Mastercam products Mill-Turn requires both a licensefor the product, and a license for each individual machine file This is different than Mastercam Mill andLathe, which only require a product license

A typical Mill-Turn installation therefore requires the following licenses:

n Mastercam Mill-Turn

n Mastercam Lathe

n One or more Mastercam Mill licenses for the desired level of Mill functionality: Mill, Mill3D , Multiaxis

n A license for each individual machine file

While Mill-Turn uses the same powerful toolpaths as Lathe, the programming environment is more

advanced and includes a number of tools to meet the demands of advanced multi-stream machines

n Mill-Turn includes a detailed Job Setup module You can select and mount w ork holdingcomponents for each job, tell Mastercam about your stock and part-handling needs, andcreates a complete set of planes and view sheets to simplify programming on each

spindle

n A separate Tool Setup Manager gives you complete control over how to organize tooling

on each turret You can completely program your turret setup w ith all of your tools

before start creating toolpaths Or you can let Mastercam do it for you after you have ated toolpaths

cre-n A set of intuitive Mill Setup types uses your Job Setup information to greatly simplify thecreation of Mill operations

n N ew tools let you create event-based part-handling operations

n Mill-Turn's Sync Manager application lets you synchronize operations in different

streams and access machine-specific options that have been created for you by yourmachine developer U se these to provide information to your machine's control that is

Mill - Turn Introduction Mill -Turn Workflow

MILL -TURN WORKFLOW

The workflow for creating a Mill-Turn job is different than other Mastercam products This is because

additional Mastercam tools, such as the Sync Manager, are required to meet the programming requirements

of advanced multi-stream machines In addition, the Mill-Turn workflow is tailored to the specific machineselected for the job Mastercam loads the proper options, settings, and part handling processes that arespecific to the selected machine before the first toolpath is created

What if I have two similar machines of different sizes? At this time you can not replace or swap the machinefile The machine you program your part on would be the machine you need to run the part on

The following outline is a typical example:

1 Load the desired machine file for the machine that you are programming See How To Add The Machine

to learn more

2 The Job Setup module launches automatically Select your chucks, jaws, and/or collets tell Mastercamabout your stock and part handling needs, and enter the proper dimensions for part stick-out and pick-offpositions Mastercam creates a set of planes with associated work offsets, viewsheets for programmingeach spindle, and supporting geometry such as turn profiles See Mill-Turn Job Setup to learn more

3 Create your turning and milling toolpaths See Lathe Toolpaths in Mill-Turn

4 When you need to transfer the part to the other spindle, perform a stock pull, or perform a similar

operation, select the proper part-handling strategy Mastercam automatically builds a sequence of individualevents that is closely tailored to your specific machine and application requirements See Part HandlingOperations (Mill-Turn) to learn more

5 Set up the tools on your turret You can let Mastercam do this automatically and edit it as necessary, or do

it completely manually See Tool Setup Manager: Mill-Turn to learn more

6 Finish programming your part in the Sync Manager This lets you create syncs or wait codes betweenstreams and access custom machine-specific options that have been created for you by your machine filedeveloper See Working with the Sync Manager to learn more

7 From the Sync Manager, launch Machine Simulation to preview the machining process and check forcollisions See Working with Machine Simulation to learn more

8 When you have proven out your part and process, post your part from the Sync Manager and generateyour NC code Your post will create the proper multi-stream output for your control, whether it is a single file

or separate files Your NC files will open in the Code Expert Editor, which has a number of tools and featuresfor working with multi-stream NC files See Working with Code Editor to learn more

ABOUT MILL-TURN MACHINE FILE

Instead of the machine definition–control definition–post architecture used in other Mastercam

products, Mill-Turn serializes these resources plus many others into a single *.machine file.

When using Mastercam Mill-Turn, the *.machine file combines the machine definition from Mastercam

Lathe with your Mill-Turn post, customizing your entire Mill-Turn experience for a specific machine tool

Hundreds of machine files are available for purchase, including models for Fanuc, Siemens, and Okuma

controls

The Machine Explorer displays the individual files that are contained in the machine file, as shown below.

The machine file can be stored anywhere on your workstation or on a network drive

The default location is:

This PC > C:\Users\Public\Documents\Shared Mastercam (version)\Mill Turn\machines

Mill - Turn Introduction Mill -Turn Workflow

GENERIC MILL-TURN MACHINES

While in general each Mill-Turn machine file requires its own individual license, generic machines areavailable for evaluation or training purposes These do not require a separate license Generic machine filesare available for a number of standard machine configurations for both Seimens and Fanuc controls:

n Single-stream tw o-spindle (Fanuc, Seimens)

n Single-stream single-spindle (Fanuc, Seimens)

n Single-stream single-spindle + tailstock (Fanuc, Seimens)

n Multi-stream tw in-turret (Fanuc)

n Multi-stream turret + B-axis head (Fanuc)

n Single-spindle + tailstock (Fanuc)

However, users of these machines still must have the proper product licenses

Note: In our example you will use the Generic Fanuc Mill - Turn TT.machine that is provided in the

software This machine is a Multi stream twin-turret that has two spindles

Turn machine files for single-stream machines with no more than one rotary axis do not require a Turn product license These can be run by any Lathe user; the only product license required is Lathe

Mill-When a Lathe user loads one of these machines, they get access to the entire Mill-Turn product (subject tothe capabilities of the specific machine) without needing to purchase a Mill-Turn license This includes thesame Machine Simulation features as the full Mill-Turn product, the ability to use component libraries andtool locators, the Job Setup module, access to the Sync Manager for machine-specific options, and the otherMill-Turn functions

Lathe users can also load and run the generic single-stream machines without purchasing an additional.machine file license
