HOWTO PROGRAM CUTTING CONDITION

Basically, the cutting conditions such as SPINDLE SPEED, FEEDRATE, and

DEPTH OF CUT use on a CNC Lathe can be determined in the same manner as

in the turning operation on a co~ventionallathe.

All the programmer has to do is to convert the conditions into the coded, digital form as -per and to register thes~ numerical information on

a) SPINDLE SPEED is specified wit~ a maximum 4-d~gits S code.

e.g If a spindle speed

m/min is required,

respectively.

b) FEEDRATE is specified with a maximum of 5-digits in Metric system

of 350 rpm or constant cutting speed of 120

it can be program as G97 S350 or G96 5120

pre-determined cutting

the data input format the process sheet.

F code.

e.g If a feedrate of 0.35 mm/rev is required, it can be programmed

as G95 FO.35.

Determining Cutting Conditions

Cutting conditions such as spindle speed, feedrate and depth of cut are selected more or less in

the same manner as witha conventional lathe. WithCNC lathes, these conditionsare entered in a

program process sheet using alphanumerics in the predetermined format. ' Formulas used to determine cutting conditions:

V=1rXDxn

where, V = cuttingspeed, m/min

1000

rr =circular constant (3.14)

Reference Point

On the CNC Lathes. there are two reference points as below: (1) Machine Origin

This is the fixed origin inherent in respective machines. where output values from the ~SP position encoders of X- and Z-axis become zero. Axis movement of the machine is referenced

to this fixed machine origin. .

(2) Program Zero (Workpiece Origin)

The zero point that can be set at any point as needed by "Zero Offset" operation; once the workpiece zero rs set. axis motion is controlled' on the coordinate system that has the origin at the set workpiece zero.

Cutting is carried out taking this point as the reference point.

A programmer should inform a machine operator of the established programming zero position either on the part drawing or with a memorandum.

Tool Offset No.

32 pairs (01 to 32) For two-spil)dle model, 32 pairs of tool

offsets are used on the individual turrets.

ToolNo.

The number identifying ihe turret face position is used as a tool number.

When the control features the toolnose radius compensation function,a T word comprises she-digit figures. (optionalfor OSP500L-G)

GSO SETTING OF MAXIMUM SPINDLE SPEED

If the maximum spindle speed is specified with a ~ digit 5 value preceded

by G50 code (G50 5 ), the actual spindle speed will not exceed the maximum RPM, .specified even when the programmed S value calls for the speed exceeding the maximum rpm of that range.

Format

N0002: .G50 53000

The actual spindle speed will not exceed 30QO rpm if the speed is specified as $4000 by mistake.

G50 command should be written in an individual block by itself.

COKPOUND FIXED CYCLE (SPECIAL FIXED CYCLE)

GENERAL DESCRIPTION

This feature allows a series of cyclic operation, which usually requires commands over several to more than ten blocks, to be specified by the Com-

mands in one block making the most of one of the features inherent in '

OSPSQQL-G/OSPSQQQL-G, high processtng speed.

There are three types of compound fixed cycle as:

(1) Thread cutting compound fixed cycle (G71, G72) (2) Grooving/drilling compound fixed cycle (G73, G74) (3) Tapping compound fixed cycle (G77, G78)

Outline of individual fixed cyclE'

(I) Thread cutting compound fixed cycle

Two modes of thread cutting cycles as Gil longitudinal thrf'"d e,lt t il!l:

cycle and G72 transverse (end face) thread cutting cycle are

available. 'In.addition, combination of M cod.e.designating ciJttilig

G75 AUTOMATIC CHAMFERING

When cutting a workpiece, it is often necessary to chamfer the sharp edge (either 45 deg. chamfering or rounding). Such chamfering can be accomplished using conventional taper and circular interpolation G codes such as GQ1, GQ2 and GU3. However, this Automatic Chamfering Function per- mits chamfering t6 be done in a simple programming.

Commands used in this feature are:

LAP

LATHE AU'1'O-PII.OG8AI FUNCTION

GENERAL DESCRIPTION

LAP (Lathe Auto-Programming) is the function to make use of high speed processing capability which characterizes the OSP500L-G/OSP5000L-G series.

With this function, the control automatically generates tool path to produce the requ~red part contour.

In this function. the program comprising, dimension data of the final

contour to be finished including rough cut conditions is prepared as the Contour Definition Program; when it is called out with the cutting conditions specified, the:control automatically generates tool- path for respective rough cut. cycles, and then finish the workpiece to the programmed dimensions.

... '1,.';0.".':

,...".' :.'" :

This feature permits the programmer to complete the part program simply picking up the dimensions specified in an engineering drawing and, there-

fore, it simplifies programming JS well as it reduces programming time; .

this furthermore facilitates tape check procedure and also tape punch\

procedure.

Various cutting modes available with the LAP can cope with any type of cutting intended.

Features of LAP are:

1) No

2) 'Tape'p're'~:ar~t~on time. can be,. gr~atly reduced. .'.: ..'

Geometrical Cutting Error Due to Too Nose Radius

If culling along paths A-B-C-D-E in Fig. 16-3 is intended without activating the tool nose radius compensation function, the portions indicated by hatching lines will remain uncut and cause a

geometrical errors. This is because the 1001setting is made to locale the imaginary cutting

point P in Fig. 16-2 al Ihe datum poinl and Irace programmed path as controlled by NC commands. However, the actual cutting tip point is not precisely located on that datum point because of the tool nos~ radius and this produces geometrical errors.

Tool Nose Radius Compensation Data

As seen. in the previous section, programming procedure to activate the tool nose radius

compensation function has been simplified. However, to finish workpieces accurately using this

function,the toolnose radius of the tool to be used must be measured precisely and the measured value entered correctlyinthe NC memory.

Measuring .Nose Radius

Measure the center of the tool nose circle with respect to the tool tip reference point which is taken

as the imaginary tool tip point for tool.presetting. See Fig. 16-6..below.

The imaginary tool tip point indicates the ideal tool tip point which can be expressed only by the tool

ollset amounts withouttoolnose R. Ac!iJally,such tools are not present. \

When the control has no tool nose radius compensation function, it controls the coordinated <j:(,!S mohon so that the tool tip reference pOintfollows the programmed path.
