1 - 2 Overview 704-0115-201 Lathe Conversational Programming

DefinitionConversational programming allows you to create a part program from a blueprint orprogram worksheet while working at the machine. Operating selections and prompts onthe screen lead you through the steps necessary to enter the data for a part program.

To create a Conversational Part Program,

1. Press the Input console key to display the Input screen. The Input screenallows you to access setup functions including Part Setup, Tool Setup, andProgram Parameters.

2. Enter machining operation information in the Part Setup and Tool Setupfunctions. This information is stored within data blocks describing eachoperation to be performed. Create and access the data blocks through theInput screen.

3. Select the PART PROGRAMMING F3 softkey to begin programming. The systemdisplays either the first block of an existing program or a New Block screen fora new program.

Data BlocksA Conversational Part Program is made up of numerically ordered data blocks that storeinformation specific to the program. Each data block contains all of the information toexecute that particular function.

Use these basic programming operations when creating data blocks:

Create a new data block or edit an existing one through the Input screen orReview screen.

Insert a new data block between two sequentially numbered blocks. The datablock is inserted in front of the one shown on the screen or highlighted in theProgram Review screen. Data blocks following the inserted block will beautomatically renumbered.

Delete an existing data block. The data blocks following the deleted blockrenumber automatically.

View a list and navigate through the part programs data blocks on theProgram Review screen.

View a list and navigate through the part programs tools on the Tool Reviewscreen.

Copy, edit, or delete information in a data block while viewing a data blockscreen.

Refer to the Getting Started with Your Max Control for TurningCenters manual for details about program planning and part and tool

setup.


11/84


Data blocks within a part program contain specific machining information:

Operation type, such as position, profile, threading, groove, hole.

Tool number to be used for the operation.

Dimension coordinates relative to X- and Z-axes.

Speed and Feedrate at which the spindle and axes move.

Speed selections are

Speed as Constant Surface Speed (CSS) in meters per minute (MPM)or feet per minute (FPM).

Speed as RPM.

Feedrate selections are

Feed per Minute in millimeters per minute (MMPM) and inch perminute (IPM).

Feed per Revolution in millimeters per revolution (MMPR) and inch perrevolution (IPR).

Locations of operations on the part.

Types of Data Blocks

The Part Programming softkeys access these types of data blocks:

Position inserts a block to select a tool and to move the tool to an X-Zlocation or pause a program for inspection. A Position block is commonly usedto move the turret to an X-Z Home location at the end of the program orwhen the tool must be moved to clearance position around the part. Refer toPosition Data Block, on page 2 - 3 for information.

Profile describes the part profile, or shape, for roughing and/or finishingoperations including tool selection, speed and feed information, clearancesand other pertinent information. Each item of the profile is described as anindividual element, such as turn, face, arc, and chamfer. Refer to Profile DataBlock, on page 2 - 6 for information.

Thread inserts a block to thread the part, whether OD (outer diameter)Straight, OD Taper, ID (inner diameter) Straight, ID Taper, or Face, includingtool selection, speed and feed information, clearances, and other information.Refer to Threading Cycle, on page 2 - 22 for information.

Groove inserts a block to put a groove on the part, whether OD, ID, or

Face, including tool selection, speed and feed information, clearances, andother information. Refer to Grooving Cycle, on page 2 - 25 for information.

Hole inserts a block to drill, center drill, or tap the part, including toolselection, speed and feed information, clearances, and other information.Refer to Hole Cycle, on page 2 - 29 for information.

Cutoff inserts a block to cut off the part including tool selection, speed andfeed information, clearances, and other information. Refer to Cutoff Block, onpage 2 - 32 for more information.

Conversational Programming CalculatorTo calculate data values for screen fields, follow these steps:

1. Position the cursor on the field you want to calculate.

2. Type the number used in the calculation.

3. Press the console key of the operation you want to perform ( + , - , x , or ).

4. Type the second number used in the calculation.

5. Press the Enter key.

To make a change to an existing field, follow these steps:

1. Select the field.

2. Type the value you want.3. Select the operation ( + , - , x , or ).

4. Press Enter .

For example, to add .05 to a field containing a value of 1.000, type .05 + then Enter . Thevalue in the field changes to 1.050.

Automatic CalculationsThe No-Calc feature automatically calculates values for certain fields after sufficient datais known. For example, if the X or Z end points cannot be determined from drawings,leave the fields blank. After you input additional information about an adjacent elementthe missing data may be calculated.

The screen displays a CAL when a calculated parameter is created. If you enter a valueand later decide to let the control calculate the data, clear the entered value by followingthese steps:

1. Use the Arrow keys to move the cursor to the parameter where the automaticcalculation is needed.

2. Press the C (Clear) console key.

3. Press the Enter key. The value is cleared from the program and the calculateddimension is displayed in its place (if the field remains blank, additional datamust be entered before the control can calculate the value).

You may repeat steps 3 and 4 for a longer equation.


14/84


Program Editing FeaturesSeveral editing features are available with the Max Control for Lathes. Keyboard andsoftware features provide you with the editing capabilities to create and update partprograms.

When changing the cutting type (for example, hole drilling or profile turning) for a datablock, a different data block must be created to describe the new cutting type. When adifferent tool is needed in a program, a new data block must be created to describe theactions of that tool. An exception is the Profile data block in which the roughing andfinishing tools can be called within the same block.

The console keyboard contains these keys:

Programming Mode keys Input, Review, and Menu keys.

Standard AT-keyboard keys Insert, Delete, Home, End, Page Up, PageDown.

Cursor Control keys Arrows, Enter, alt, C, and F function keys.

38/84


Blend Arc A Blend Arc operation creates a curved line that joins two other elements and is tangentto both.

Figure 210. Blend Arc Element screen

A blend arc can be used to join these types of elements:

two Face elements.

a Face element and a Turn element.

two Arc elements.

a Taper to another element.

The elements to be joined must have a theoretical point of intersection. If the onlyinformation known about an arc is its radius, it is easier to program it as a blend arc, if the elements intersect.

Here are some guidelines that must be followed when creating a blend arc or chamfer:

The first or last element of a Profile data block cannot be blend arc orchamfer elements.

Blend arc or chamfer elements cannot be adjacent to one another in aprogram. For example, if Element 2 is a blend arc, neither Element 1 nor 3can be blend arc elements.

Elements that are adjacent to the blend arc or chamfer element mustintersect at some point in their theoretical plane. Therefore, if Element 2 is ablend arc, Elements 1 and 3 must theoretically intersect at some projectedpoint.

The radius of a blend arc or chamfer element cannot be too large to betangent to both of the adjoining elements

If any coordinate (start point, center point, or end point) is important to theconstruction of the two elements to be blended, the element must beprogrammed as an arc and not as a blend arc or chamfer.


39/84


The Feed field is initially displayed with a value carried forward from theprevious element. This value can be accepted or changed.

These fields are available for programming a Blend Arc Element:

X END (DIA) or (RAD) contains the X coordinate for the ending point of the blend arc carried over from the previous element.

Z END contains the Z coordinate for the ending point of the blend arccarried over from the previous element.

X CENTER (D) or (R) contains the X coordinate of the blend arcs centerpoint.

Z CENTER contains the Z coordinate of the blend arcs center point.

RADIUS identifies the radius of the blend arc.

Reference values for X Start (DIA) or (RAD) and Z Start on the right-hand side of the

screen are programmed in the previous element or Profile Start screen and define thestart of this element. They can only be changed in the element in which they werecreated.



40/84


Chamfer A Chamfer operation creates a straight line that joins two other elements and is tangentto both.

Figure 211. Chamfer Element screen

A chamfer can be used to join these types of elements:

two Face elements.

a Face element and a Turn element.

two Arc elements.

a Taper to another element.

The elements to be joined must have a theoretical point of intersection.

Here are some guidelines that must be followed when creating a blend arc or chamfer:

The first or last element of a Profile data block cannot be blend arc orchamfer elements.

Blend arc or chamfer elements cannot be adjacent to one another in aprogram. For example, if Element 2 is a blend arc, neither Element 1 nor 3can be blend arc elements.

Elements that are adjacent to the blend arc or chamfer element mustintersect at some point in their theoretical plane. Therefore, if Element 2 is ablend arc, Elements 1 and 3 must theoretically intersect at some projectedpoint.

The radius of a blend arc or chamfer element cannot be too large to betangent to both of the adjoining elements.

If any coordinate (start point, center point, or end point) is important to theconstruction of the two elements to be blended, the element must beprogrammed as an arc and not as a blend arc or chamfer.
