Lathe problem

[MSL]

Hi

I'm trying to see the way my tool is set up and cuts on my machine.

We have a machine that is not a full cnc lathe(dosen't have tool turret, like haas TL's).

I went to tool set up and select bottom turret, also I changed my planes to D-Z+. It didn't work on the machine. What should I try?

using X4.

Thanks.

for the haas toolroom style lathe, just use the basic configuration with an upper turret. It "looks" like it's cutting turret lathe sytle, but when you post it will be correct.

Thanks Chris,

How can I see it in my verify? I want to see my tools cutting from bottom turret.

Thanks.

Well it can be done, but you will need to become a post expert pretty quick. In the lathe post there is a part that allows you to switch the matrix of the machine so you get the results of what you are after. I will point you in the right direction, but again as always with post make sure you have a back up copy before starting any post modifications. Will have to use the Generic 4 axis lathe post since the Basic 2 axis lathe post does not have these settings.

 

code:

#Machining position turret/spindle settings

# Switch strings based on turret position top/bottom-left/right and cut type.

# Turret position is based on the Mastercam settings (see lathtype).

# Strings are re-assigned for output in the routine psw_str_mult.

# The string variable sw_string holds the place position value to determine

# how to assign the strings. Planes are relative to the view from Mastercam.

# Assign the 17 digit string following the alpha columns below:

# A - C axis, 1 = axis winds, 2 = axis signed, 3 = indexer

# B - Spindle direction, 0 = normal, 1 = reverse

# C - Plane 0 arc/comp, 0 = normal, 1 = switch

# D - Plane 1 arc/comp, 0 = normal, 1 = switch

# E - Plane 2 arc/comp, 0 = normal, 1 = switch

# F - Plane 0, 0 = G17, 1 = G19, 2 = G18

# G - Plane 1, 0 = G17, 1 = G19, 2 = G18

# H - Plane 2, 0 = G17, 1 = G19, 2 = G18

# Decimal (required)

# I - Plane 0, X axis, 0 = normal, 1 = switch sign from basic

# J - Plane 0, Y axis, 0 = normal, 1 = switch sign from basic

# K - Plane 0, Z axis, 0 = normal, 1 = switch sign from basic

# L - Plane 1, X axis, 0 = normal, 1 = switch sign from basic

# M - Plane 1, Y axis, 0 = normal, 1 = switch sign from basic

# N - Plane 1, Z axis, 0 = normal, 1 = switch sign from basic

# O - Plane 2, X axis, 0 = normal, 1 = switch sign from basic

# P - Plane 2, Y axis, 0 = normal, 1 = switch sign from basic

# Q - Plane 2, Z axis, 0 = normal, 1 = switch sign from basic

Now change the correct turret combination the correct numbers to use are explained in the 1st part. Change one setting for that turret configuration at a time then test keep doing this till everything is that way you want.

 

The Basic 2 axis lathe post might have a switch, but I do not think it supports lower turret. Also I would look to the MPLMASTER lathe post from IN-HOUSE that is free off of this web site it has tons of bells and whistles, but the idea is you guys progress get better equipment and grow into that 3 turret lathe with dual spindles where all 3 turrets have Y axis milling capabilities and that post has give you building block at least with code capabilities to get there.

 

Now if you are unsure on modifing the post then either deal with it looking like it does which works fine and make perfectly good parts or contact your dealer and have them quote you making a post and machine definition so it will look like you want it on the screen.

Thanks Ron,

I'll try this.
