C-axis with 360 degree

[Madhu]

Hi,

 

I have lathe with c axis, it can take 0 to 360 degree only. Now I don't know how to limit in post. Please any one can suggest me how to put in.

 

regards

I am going to go on a whim here.

Look for rotary axis settings.

Look for one_rev. change 0 to 1

 

I think this is it,but not positively sure.

 

 

one_rev : 1 #Limit rotary indexing between 0 and 360? (0 = No, 1 = Ye

If you are useing mplfan.pst look for the following settings.

 

#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

 

Note: Look at setting A

I am not getting the result, I tried by changing in all below,

 

I am going to try with loops.

 

 

#C-axis variables for calculations

c_axistype : 1 #1 = C axis winds-up, 2 = C axis signed absolute

#3 = index positioning (do not set here, use string)

ipr_type : 0 #Feedrate for Rotary, 0 = UPM, 1 = DPM

csav : 0 #Initial c axis result from pxyzcout call

czero_csav : 0 #Save csav when circle at zero detected

c_wnd : 0 #Calculation for c axis position tracking (abs-wind)

prvc_wnd : 0 #Saved cout calculation from deg., this is cabs in mpfan

rev : 0 #C axis wind-up multiplier

prvfrdeg : 0 #Feedrate deg/min actual

circum : 0 #Circumference

ldelta : 0 #Linear distance for deg/min, linear

cdelta : 0 #Total linear and angular motion for deg/min

cldelta : 0 #Calculation for deg/min, linear and rotary

sav_rev : 0 #Saved revolution counter

indx_out : c9k #Rotation direction calculation

fmt 17 frdeg #Feedrate deg/min actual

fmt 20 indx_mc #Rotation direction calculation

You need to change it under the letter A look at my prvious post, the A columns all = 2 . Under the letter A you need to set all the # 1 to # 2.
