How to make production plan in auto parts machine shop?

How Does An Auto Parts Machining Workshop Make A Production Plan? For Example, If An Order For 1,000 Pieces Is Received Delivery Is Required In 5 Days, The Production Plan Is First Broken Down, The Production Target Is Determined Based On The Company's Monthly Plan, The Workshop's Weekly Plan, The Team's Daily Plan.

The Relevant Parameters For Formulating Production Plans For CNC Precision Machining Of Automotive Parts Are Mainly The Following:

1. Determine The Input Time For The Shift. For Example, If The Working Hours Are 08:25~17:30, The Input Time Is 9 Hours 5 Minutes. Plan The Downtime Loss Time, The Fixed Loss Time Every Day, 5 Minutes For The Class Meeting, 60 Minutes For Lunch Rest Time, 30 Minutes For 5s Time, 30 Minutes For The First Inspection Time. The Load Time Is 7 Hours.

2. Determine The Standard Working Hours. CNC Precision Machining Is The Equipment Process Cycle + Employee Clamping Operation Time. The Employee Clamping Time Is Measured By A Stopwatch Is The Normal Working Time Of Skilled Employees. For Example, The Process Cycle Is 400s, The Clamping Time Is 30s, The Total Is 430s/Piece (Takt Time).

3. Calculate The Normal Output Per Shift. For Example, The Normal Output For 7 Hours Is 7*60*60/430=58 Pieces/Shift.

4. Include This Output In The Production Table. When The Auto Parts Processing Product Is A Unit With Multiple Processes Belongs To A Single Flow, If The Processing Efficiency OP1 Is 430s/Piece, OP2 Is 380s/Piece, OP3 Is 360/Piece, The Bottleneck Process OP1 Can Be Calculated.

5. When There Is Time Loss Due To Planned Equipment Maintenance Product Replacement, The Time For Each Product Replacement Needs To Be Replaced Converted Into Output Eliminated The Shift Plan.
